Abstract
The reaction of silver triflate (AgOTf) and silver dodecyl sulfate (AgDOS) with two nonmesomorphic 4,4'-disubstituted 2,2'-bipyridines, L-n, yielded a series of bis-chelate ionic silver complexes [Ag(L-n)(2)]X. Complexation induced columnar mesomorphism in all the silver(I) tetra-branched bipyridine derivatives and the role of the counterion proved to be crucial in the generation of different symmetries of the mesophase. Remarkably, all silver(I) complexes exhibit emission at room temperature both in solution and in the solid state. ((c) Wiley-VCH Verlag GmbH & Co.
