相转移催化合成酯基取代酞菁铜及其光导性能

酞菁配合物的大π键共轭体系使其具有独特的物理化学性能．但酞菁的难溶性，限制了其进一步的研究和应用．Baker等首次制备了可溶性酞菁单分子膜，并将其应用到光电池中；随后，已有大量的相关研究报道．作为常见的可溶性酞菁衍生物，酯基取代酞菁由于含酯基的前体物质高温分解而不能采用直接缩合的方法，

Synthesis of Ester Substituted Copper Phthalocyanines by Phase Transfer Catalysis Reaction and Their Photoconductivity

Copper-tetra-4-(butyloxycarbonyl) phthalocyanine, copper-tetra-4-(octyloxycarbonyl) phthalocyanine and copper-tetra-4-(dodecoxycarboxyl) phthalocyanine were synthesized by the phase transfer catalysis reaction. The reaction has several advantages in comparison with the previous carboxyl-esterified method, such as the milder conditions, the shorter reaction time(3—6 h), the higher yield(>95%), and so on. Because of the difference in the substituent group length of these compounds, the morphology and the congregation of the molecules in their casting films is different, leading to the different photoconductivities of them.
