摘　　要：　研究了磺化2,3-萘酞菁锌(Ⅱ)、钴(Ⅱ)在DMF(N,N-二甲基甲酰胺)、DMSO(二甲基亚砜)、乙醇、水等溶剂中的电子吸收光谱和荧光光谱.萘酞菁配合物的Q带与相应的酞菁配合物Q带相比,电子吸收光谱红移80～90nm,荧光光谱红移约100nm,荧光强度也显著增加.在金属萘酞菁中引入磺酸基,配合物的电子吸收光谱Q带发生红移,但是影响不大.对于相同中心金属的配合物,改变溶剂的种类对配合物的电子吸收光谱的Q带影响较大.在金属萘酞菁环上引入一个磺酸基时,在相同溶剂中与无取代萘酞菁相比发生荧光光谱Q带红移,荧光强度增大.但在萘酞菁环上继续引入磺酸基时,荧光强度反而减少.磺化萘酞菁钴比磺化萘酞菁锌有较大的荧光强度.不同浓度下的电子吸收光谱和荧光光谱说明金属萘酞菁有集聚倾向、能形成基激缔合物.The electronic absorption spectra and fluorescence emission spectra of sulfonated naphthalocyanine zinc(Ⅱ)and sulfonated naphthalocyanine cobalt(Ⅱ)were investigated respectively in the solutions of N,N-dimethylformamide (DMF),dimethy1 sulphoxide (DMSO),ethanol,and water.Compared with those of the corresponding phthalocyanines,the Q bands of naphthalocyanines had a red shift of 80 to 90 nm for the electronic absorption spectra and of 100 nm for fluorescence emission spectra.And the intensities of fluorescence Q bands were enhanced for naphthalocyanines.There was a red shift to the Q band of electronic absorption spectrum when the naphthalocyanine was sulfonated,but the effect was not large,while the solvent effect on the Q band was large.When there was only on sulfogroup on the naphthalocyanine ring,there was a red shift for the Q band of the fluorescence spectrum,too.And the intensity of fluorescence was also enhanced.But as more sulfogroups were introduced to the ring,the intensities of fluorescence were decreased.The fluorescence intensity was larger for sulfonated naphthalocyanine cobalt(Ⅱ)than for sulfonated naphthalocyanine zinc (Ⅱ).The formation of excimer and the tendency of aggregation were shown by changing the naphthalocyanine concentrations of the solution.
