Polydiacetylenes in organic-inorganic hybrid systems

Mono- and di-ammonium chloride salts with butadiyne moieties were synthesized and they were combined with cadmium chloride in thin film forms. Layered perovskite structures were confirmed for spin-coated films of bis(10,12-nonadecadiynylammonium)tetrachlorocadmate 26 and bis(10,12-heptacosadiynylammonium)tetrachlorocadmate 27 and Langmuir-Blodgett films of 27. After UV irradiation, blue-colored polydiacetylene incorporated in the layered perovskite structure was obtained for the spin-coated films of 27.
