摘要: A series of phthalocyanine-C60 dyads 2a–d was synthesized. Key steps in their synthesis are preparation the low symmetry phthalocyanine intermediate by statistical condensation two phthalonitriles, and final esterification fullerene derivative bearing a free COOH group. Structural characterization molecules solution performed NMR spectroscopy, UV–vis spectroscopy cyclic voltammetry. Preliminary studies suggest formation liquid crystalline (LC) mesophases for some prepared dyads. To best our knowledge, this is first example LC
