Bisubstituted-biquinoline Cu(<scp>i</scp>) complexes: synthesis, mesomorphism and photophysical studies in solution and condensed states

Abstract

New ionic Cu(<sc>i</sc>) coordination complexes with 4,4′-bisubstituted-2,2′-biquinolines showing low temperature lamello-columnar and columnar hexagonal thermotropic mesomorphism, depending on the substituents, are synthesized and characterized.
