Functional Materials (CN, PN, SN)

Prof. Axel Schulz

 

Starting from new CN-, PN- and SN-species we are interested in binary oligomers or polymers. In combination with properties like hardness, magnetism, light absorption and low melting points we want to arrive at interesting materials (polymers: CN- and PN-chemistry hard materials: CN-chemistry, ionic liquids: resonance stabilized methanides and amides, SN-chemistry molecular magnets etc.). In addition, quantum mechanical methods are used to calculate thermodynamic and kinetic data as well as electron density and charge distributions (population analyses such as AIM, NPA, etc.) to estimate physicochemical properties or used for a better understanding of the structure ↔ bonding ↔ property relationship.

An example from current research represents the targeted synthesis of several new ionic liquids (melting point < 20°C) based on resonance-stabilized methanides.

Although resonance-stabilized methanides represent energetic materials, they are sufficiently kinetically stabilized (decomposition temperatures above 150°C) to find application.

Of interest in terms of application could be the intense colors of such liquids based solely on electronic n-π* excitations in the anion.
