Organosilicon and organotin hydrides have been studied as precursors in the formation of nano-sized polymeric materials which consist of a backbone of covalently bonded metal atoms. These materials feature an increased degree of electron delocalization and may therefore be interesting for the use in charge-transfer devices and Li-ion batteries. We focused on the synthesis, characterization and possible application of differently substituted arylsilicon and aryltin hydrides and their respective nanoparticles and nano-sized polymers.
Moreover we synthesized aryl-substituted silicon and tin hydrides of the types R3EH, R2EH2 and REH3 (R = phenyl, 1-naphthyl; E = Si, Sn) as precursor materials and characterized them using cyclic voltammetry. The precursors were then pyrolysed or polymerized, respectively, and the resulting nanoparticles were incorporated within anodes of Li-ion batteries.
Herein we report first electrochemical characterization of differently aryl-substituted silicon and tin hydrides using cyclic voltammetry methods. Additionally, these precursor materials as well as their respective nanoparticles were tested as anode materials in Li-ion half-cells.
