New 4'-alkyl-substituted 2,2':6',2''-terpyridine (4'R-terpy) compounds have been synthesised from 4'-methyl-2,2':6',2''-terpyridine and an appropriate 1-bromoalkane and complexed with ruthenium and rhodium to yield new bis(terpyridine) complexes (2+) (R = C19H39 or C31H63) and (3+) (R = C19H39) as chloride and hexafluorophosphate salts.These complexes are amphiphilic being structurally related to surfactant tris(bipyridine)ruthenium complexes.Both ruthenium and rhodium complexes with R = C19H39 and chloride counter ions show lyotropic mesomorphism in water, and the ruthenium complex with R = C31H63 shows mesophase formation in ethylene glycol.
