Mesomorphic stilbazole complexes of silver(I) with triflate and nitrate counter-anions

Authors


Abstract

Reaction of AgX (X [DOUBLE BOND] NO3 or CF3SO3) with two equivalents of 4-alkyloxystilbazole leads to the mesomorphic silver(I) complexes [Ag(n-OPhVPy)2] [X] in high yield. The long-chain homologues of each series show SA and SC mesophases, while for shorter chain lengths the nitrate salts show only an SA phase and the triflate salts only a nematic phase. The phase behaviour of these new complexes is discussed in relation to analogous complexes with different counter-anions or ligands.
