Research edit

 
Porous nanosized spherical polyoxomolybdate based capsule Mo132: the 20 stepwise closable pores with crown-ether function are filled with guanidinium cation-guests (sphere surface supramolecular chemistry).

His current research relates mainly to bottom-up pathways towards tailor-made spherical porous metal oxide nanocapsules Mo132 Keplerates. Müller's discovery of the molecular giant spheres (Keplerates) of the type Mo132 (diameter ca. 3 nm) and their derivatives,[1][2][11] of the wheel shaped cluster Mo154 (Refs.[1][2] and [12][13][14]) and hedgehog shaped cluster Mo368[1][2] (as large as 6 nm) has caused a paradigm shift due to the unique structural features and huge application range of these molecular nanoclusters[citation needed].

The capsule has 20 well-defined pores with crown-ether functions which may be reversibly opened and closed. Substrates enter through these pores, and they can react to form a variety of species depending on the internal tapestry of the nanocontainer. This inorganic nanocell also allows ion transport through the cavity. Several new phenomena under confined conditions can be studied by variation of the internal ligands with hydrophilic and/or hydrophobic character, based on a variety of reactive substrates inside (for the interdisciplinary character of the whole compound class see Ref.[15]). These single molecules are quite large; this can be shown by taking the length of an oxygen molecule with two atoms (length 0.12 nm) as a unit, then considering Mo368 which is 50 times larger.

All the mentioned nanomaterials belong to a class commonly termed polyoxometalates and some special ones to the molybdenum blue family; the elucidation by Müller of the chemical nature of molybdenum blue was a real tour de force.[16][17]

There are two older synthetic topics where Achim Müller did pioneering work. This refers to basic simple transition metal sulphur compounds, including related hydrodesulfurization catalysis and a new type of host guest chemistry based on polyoxovanadates[3][4][5][6] (for both topics see especially the three Honorary Issues under Bibliography). One paper about polyoxometalates was cited ca. 2000 times.[18] The publications of Achim Müller were highlighted many times in the media and related magazines.[19] Important last sentences: “Giant polyoxometalates (POMs) are of particular interest, as they are the largest inorganic molecules ever made, combined with fascinating structures and manifold applications in catalysis, medicine and material sciences. Typically, Müller‘s group has achieved great success in creating giant polyoxomolybdates (POMos) during the past two decades, establishing a series of incredibly large POMos with hundreds of Mo centers, such as {Mo132}, {Mo154}, {Mo176}, {Mo248} and {Mo368}. Especially {Mo368}, with more than 360 Mo atoms, still is the largest POM to date...“[20]

Applications and Impact edit

These are soluble in water and are very probably one of the most versatile materials regarding applications in nanoscience.[1][2] It is evident that such applications are of interest not only for chemistry but also for biology, supramolecular chemistry and materials science as well as discrete mathematics. The applications include the following topics:

  • Investigating processes, including catalytic ones, under confined conditions, especially in capsules with stepwise tunable pores and tunable internal functions
  • Coordination chemistry at surfaces, in pores and in cavities of nanocapsules: sphere-surface supramolecular chemistry, controlled exchange of guests at different internal sites with each other and with the outside, nano ion-chromatography, nucleation processes under confined conditions
  • Modelling ion transport across transmembrane channels
  • New insights into hydrophobic interactions, e.g. thermodynamics of hydrophobic clustering, sequestration of hydrophobic organic pollutants, and nano-dewetting
  • Structure and dynamics of encapsulated high and low density water
  • Towards multifunctionality and hierarchical complexity: examples for chemical adaptability and for a supramolecular chemical Darwinism, self-assembly of capsules into various patterns in different phases (e.g. blackberry-like hollow spherical assemblies as well as two- and three-dimensional structures)

Müller's related work shows many applications (see above), for example, how cellular processes like ion-transport can be modelled based on the spherical porous capsules[21][22] and how the latter can be used to remove toxic compounds from water.[23]

The compounds are studied worldwide by many groups especially in relation to potential applications in Materials Science (see Ref.[1][2] and below). One aspect is modelling of the Lotus effect,[24] another one is chemical adaptability as a new phenomenon.[25]

An interesting mathematical treatment of the Keplerates could be developed in relation to spherical viruses and Buckminster Fuller Domes based on Archimedean and Platonic solids.[26] The unique range of potential applications of the Mo132 Keplerates has also been highlighted by several other authors, e.g.:[27] "Thus, Keplerate-type capsules represent unique supramolecular objects offering a tunable spatially-restricted environment and promising in many domains such as catalysis, electric conductivity, non-linear optics, liquid crystals, vesicles and "blackberry" aggregates. ...a key point to promote confined space engineering." In another publication[28] it is written: "Initiated and led by Müller and co-workers, the synthesis and structural characterization of protein-sized metal oxide clusters (2-6 nm) have generated great interest in the areas of physics, biology, chemistry, and materials science"; see also regarding a similar comment Ref.[29] Some of the clusters can be obtained by planned synthesis,[30] while the related derivative (also because of the structure of a Keplerate[31][26]) Mo72Fe30 has unique magnetic properties.[1][2][31]

Personal edit

Müller likes ancient Greek philosophy, classical music, and mountain hiking. He has a love for woodland birds since his early childhood, a pastime which his father cherished also.

  7. ^ Müller’s work on a new type of isopolyoxovanadates has provided some of the most instructive examples of host-guest inorganic chemistry, leading to the recognition that a polyoxometalate is a supramolecular species involving a negatively charged host cage and a negatively charged encapsulated guest, and hence opening a new era in polyoxometalate chemistry. The template self-organization of an ”electronically inverse host” around a negatively charged guest might seem somewhat puzzling: According to theoretical studies, this follows from the fact that electrostatic repulsion is overcome by maximizing the molecular electrostatic potential at the guest

large POMos with hundreds of Mo centers such as Mo132 Mo154 Mo176 Mo248 and Mo368 Especially Mo368 with more than 360 Mo atoms still is the largest POM to date 20 Applications and Impact edit These are soluble in water and are very probably one of the most versatile materials regarding applications in nanoscience 1 2 It is evident that such applications are of interest not only for chemistry but also for biology supramolecular chemistry and materials science as well as discrete mathematics The applications include the following topics Investigating processes including catalytic ones under confined conditions especially in capsules with stepwise tunable pores and tunable internal functions Coordination chemistry at surfaces in pores and in cavities of nanocapsules sphere surface supramolecular chemistry controlled exchange of guests at different internal sites with each other and with the outside nano ion chromatography nucleation processes under confined conditions Modelling ion transport across transmembrane channels New insights into hydrophobic interactions e g thermodynamics of hydrophobic clustering sequestration of hydrophobic organic pollutants and nano dewetting Structure and dynamics of encapsulated high and low density water Towards multifunctionality and hierarchical complexity examples for chemical adaptability and for a supramolecular chemical Darwinism self assembly of capsules into various patterns in different phases e g blackberry like hollow spherical assemblies as well as two and three dimensional structures Muller s related work shows many applications see above for example how cellular processes like ion transport can be modelled based on the spherical porous capsules 21 22 and how the latter can be used to remove toxic compounds from water 23 The compounds are studied worldwide by many groups especially in relation to potential applications in Materials Science see Ref 1 2 and below One aspect is modelling of the Lotus effect 24 another one is chemical adaptability as a new phenomenon 25 An interesting mathematical treatment of the Keplerates could be developed in relation to spherical viruses and Buckminster Fuller Domes based on Archimedean and Platonic solids 26 The unique range of potential applications of the Mo132 Keplerates has also been highlighted by several other authors e g 27 Thus Keplerate type capsules represent unique supramolecular objects offering a tunable spatially restricted environment and promising in many domains such as catalysis electric conductivity non linear optics liquid crystals vesicles and blackberry aggregates a key point to promote confined space engineering In another publication 28 it is written Initiated and led by Muller and co workers the synthesis and structural characterization of protein sized metal oxide clusters 2 6 nm have generated great interest in the areas of physics biology chemistry and materials science see also regarding a similar comment Ref 29 Some of the clusters can be obtained by planned synthesis 30 while the related derivative also because of the structure of a Keplerate 31 26 Mo72Fe30 has unique magnetic properties 1 2 31 Personal

recognition that a polyoxometalate is a supramolecular species involving a negatively charged host cage and a negatively charged encapsulated guest and hence opening a new era in polyoxometalate chemistry The template self organization of an electronically inverse host around a negatively charged guest might seem somewhat puzzling According to theoretical studies this follows from the fact that electrostatic repulsion is overcome by maximizing the molecular electrostatic potential at the guest For example a Die inharente Potentialitat materieller chemischer Systeme A Muller Philosophia
