摘要: The synthesis and spectroscopic characterization of novel manganese(III) phthalocyanines bearing 7-oxy-4-(4-methoxyphenyl)-8-methylcoumarin or/and chloro groups have been achieved. effect alpha beta substitution on the ligand- metal-based reduction processes manganese phthalocyanine complexes their interaction with dioxygen were investigated. more effective central metal coumarin substituted complex than that its analogue was attributed to hindrance by nonplanarity in case substitution. Similarly, aggregation tendency lower Among fabricated coumarin-substituted donor layer fullerene (C60) acceptor based photovoltaic heterojunction devices, one containing 8 exhibited best performance. thickness active Pc solar cell parameters has also A nearly independent open circuit voltage observed.
