Abstract
The possibility of cryoformation and chemical transformations of new metallomesogenic complexes, exemplified by co-condensates of silver with carbon tetrachloride in the matrix of mesogenic 4-n-pentyl-4′-cyanobiphenyl, has been studied by EPR. Four types of paramagnetic products were detected in this system at low temperatures: biligand π-complexes of silver atoms with cyanobiphenyl molecules; σ-complexes of silver atoms with the cyanobiphenyl molecule stabilized by an additional electron acceptor ligand CCl4; trichloromethyl radical adducts of silver chloride — AgCl·CCl •3 and silver nanoclusters formed as a result of aggregation of silver atoms. Thermal stability of these particles was examined and a possible mechanism of their chemical transformations was proposed.
