摘 要:以吡咯和甲氧基苯甲醛为反应起始物,在水和甲醇溶剂中采用改进的Lindsey法合成了4-甲氧基苯基咔咯(a)和2,4-二甲氧基苯基咔咯(b)两种无金属甲氧基苯基咔咯配合物。测定了配合物在二氯甲烷溶剂中的紫外-可见及荧光光谱。发现配合物a和b的Soret分别位于418和420 nm,Q吸收峰则分别位于570、608、645 nm和576、619、656 nm波长处;而配合物a、b的荧光发射光谱分别在683和661 nm波长处的强度最大。用红外、核磁共振、质谱等光谱技术对配合物进行了结构表征,结果表明所得产物即为目标配合物。Two free-base methoxyphenylcorrole complexes, 5,10,15 -tris( 4-methoxyphenyl ) corrole ( a ) and 5,10,15 -tris (2,4-dimethoxyphenyl) corrole ( b ) were synthesized using the improved Lindsey method by a reaction of methoxybenzaldehyde and pyrrole in methanol-water solutions. The UV-visible and fluorescent spectra of the complexes were measured in CH2Cl2. The Sorer band located at 418 and 420 nm,Q bands at 570,608,645 nm and 576,619,656 nm for complex(a) and(b) , respectively. The maximum intensity of the fluorescence emission spectrum is at 683 nm for corrole(a) and at 661 nm for( b). The structure of corroles was characterized by FTIR,^1 HNMR and MS techniques. The results indicated that the products obtained are the expected corrole complexes.
