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。
In this paper, two new asymmetric substituted copper phthalocyanine complexes were synthesized from phthalimide: 4- (p-carboxyphenoxy) -tri-4- (2,4-dipentyl Phenoxy) phthalocyanine copper (IV) and 4- (o-aminophenoxy) -tri-4- (2,4-dipentylphenoxy) copper phthalocyanine (V). Its structure was characterized by elemental analysis, infrared spectrum, nuclear magnetic resonance spectrum, mass spectrum, paramagnetic resonance spectrum and ultraviolet spectrum. Both complexes are easily soluble in dichloromethane, chloroform and toluene and other organic solvents, do not dissolve in water. The complex of chloroform solution can be developed on the water to form a monolayer. π-A curve shows that the complex decreases with the increase of surface pressure on the liquid phase (water) of the subfacies, showing a continuous “gas” and “solid” process, indicating that the complex Can form a better LB film. Molecules are mainly arranged in a sloping manner in the film. The LB film deposited on the gold comb electrode in a Z-shaped manner can be electrically conductive and belongs to a semiconductor material. Iodine doping improves the conductance of the film. The gas-sensing properties of the membrane electrode revealed that the complex has a unique gas-sensing property for ammonia gas, that is, the ammonia gas has a response of 33 ppm and has high sensitivity.
