摘　　要：本文以邻苯二甲酰亚胺为原料,合成了两种新的非对称取代酞菁铜配合物:4-(对羧基苯氧基)-三-4-(2,4-二特戊基苯氧基)酞菁铜(Ⅳ)和4-(邻氨基苯氧基)-三-4-(2,4-二特戊基苯氧基)酞菁铜(Ⅴ)。并经元素分析、红外光谱、核磁共振谱、质谱、顺磁共振谱及紫外光谱,对其结构进行了表征。两种配合物都易溶于二氯甲烷、氯仿和甲苯等有机溶剂,不溶于水。配合物的氯仿溶液能在水面上展开形成单分子膜。π-A曲线测定表明,配合物在亚相液面(水)上,随着表面压力的增大,膜面积连续不停地减少,有明显的“气”“固”变化过程,表明配合物能形成较好的LB膜。分子在膜中主要以倾斜的方式排列。以Z型累积方式沉积于金制梳状电极上的LB膜能导电,属于半导体材料,碘掺杂可改善膜的电导。膜电极的气敏特性研究发现,配合物对氨气有专一的气敏特性,氨气浓度为33ppm时即有响应,且灵敏度高。The following two new asymmetric derivatives of phthalocyanine copper, have been synthesized and ascertained through elemental analysis, IR, 'H-NMR, ESR and UV spectra. The complexes are soluble in organic solvents such as dichloromethane, chloroform and toluene very easily, but insoluble in water. The pressure-area isotherms for the complexes show that the complexes have good film-forming ability and the molecules are sloping in the films. The LB films deposited on gold comb electrode by the LB technique according to the Z-type belong to semiconductor, and their conductance can be enhanced by doping iodine. The gas-sensibility of LB films was determined. The results show that the films has good sensibility and selectivity for the vapor of NH3.
