摘　　要：通过4-硝基邻苯二甲腈先成环,后修饰的合成步骤,得到对咪唑苯甲醛与酞菁环通过希夫碱基团直接桥连的β-四(4-咪唑基苯基)亚氨酞菁锌(SPc)。通过红外光谱、核磁共振氢谱表征了其结构,进行了紫外可见光和荧光光谱测试。研究发现SPc在吡啶中溶解性最好,在一定的浓度范围之内,SPc分子间没有聚集行为,摩尔吸光系数与浓度成正比。SPc在DMF溶液中紫外-可见光吸收峰Q带位于693 nm,与无取代酞菁锌相比,Q带红移了26 nm。445 nm激发波长下,荧光发射波长为560 nm。The compound β-tetra-{[4-（1H-imidazol-1-yl）benzylidene]amino} zinc phthalocyanine （SPc） was synthesized according to cyclotetramerization of 4 -nitrophthalonitrile and introduce 4 -（ 1H -imidazol -1 -yl ） benzaldehyde through CH =N bond.The structure of SPc was characterized by FTIR , 1 H NMR, UV-vis and fluorescence spectrum.It was found that SPc had the best solubility in pyridine.Within the certain concentration range , there was no aggregation between SPc molecules , and the molar absorption coefficient was in direct proportion to concentration .The Q band of SPc located in 693 nm when it was dissolved in DMF , redshifted 26 nm compared to the unsubstituted zinc phthalocyanine.When the excitation wavelength was 445 nm, the emission wavelength was 560 nm.
