单氨基取代3∶1不对称酞菁锌的合成及其在有机溶剂中聚集状态的研究

Synthesis of 3∶1 Monoamino Substituted Asymmetrical PhthalocyanineZinc(Ⅱ) and Aggregative Behavior in Organic Solvents

酞菁(Phthalocyanine,Pc)金属配合物是一类性能优异、应用广泛的功能材料.由于酞菁类配合物有18共轭π电子,使其具有许多独特的物理化学性质,已经成为一种性能良好的多功能材料,在催化化学、光化学、电化学、非线性光学、信息存储学、医学等学科的前沿领域及相关的高新技术领域都有着广泛而重要的应用潜力和发展前景[1,2].因而,近年来引起人们越来越浓厚的研究兴趣.

Monoamino substituted asymmetrical phthalocyanine zinc（Ⅱ）, 2-amino-9,10,16,17,23,24-hexapentyloxy phthalocyanine zinc（Ⅱ）, was synthesized by statistical condensation and characterized by elemental analysis, UV- Vis, IR and TOF-MS. The aggregative behavior was studied in DMF, THF and CH2Cl2. The results show that it is not aggregateve in DMF and THF, whereas form dimer in CH2Cl2 at 8 × 10^-7-8 × 10^-6 mol·L^-1. The equilibrium constant for the dimer was calculated at the same time, indicating that the less polar solvent is unfavorable for the presence of the monomer.
