摘　　要：用紫外-可见吸收光谱对金属酞菁及其衍生物进行研究,分析了酞菁的不同d电子数、不同价电子数和不同取代基对Q带和B带的影响。研究结果表明,d电子数增加,HOMO-LUMO分子轨道间能级差降低,电子光谱发生红移。金属酞菁中金属电荷对Q带影响不大,而随着电荷的增加,对B带有一定影响。Schiff基团的引入对Q带产生一定的影响,前线轨道能级裂分导致Q带红移并出现了不同程度的裂分。特别是二茂铁基团的酞菁金属配合物具有极高的非线性光学性能,有望开发成用于光动力诊疗的新型光敏剂。The metal phthalocyanine and its derivatives were studied by UV-Vis absorption spectra. And the effects of their different d-electron number,valence electron number and substituents on Q-band and B-band were analyzed. The results showed that with the number of d-electrons increasing,the energy difference between HOMO-LUMO molecular orbitals decreased, and its Q-band had a distinct red shift. The metal charge in phthaloeyanine barely affect the Q-band, while the B-band was ilfflueneed to some degree by the increase of charge. Moreover,the introduction of Sehiff base had an impact on the Q-band. The fracture of the front orbital energy level leaded to the red shift of Q-band and more or less splitting emerged. Among the derivatives, ferroeene-based phthaloeyanines complexes showed especially excellent performance on nonlinear optical property-. Therefore,it had a bright prospect to be developed as a new photosensitizer for photodynamie therapy（PDT） and photodynamie diagnosis（PDD）.
