摘要(Abstract):

目的:将四苯基卟啉(H2TPP)及其衍生物作为研究对象,测定其荧光光谱和荧光量子产率,从而筛 选出较好的光敏剂。方法:采用荧光分析法测定不同条件下的荧光光谱,采用参比法测定样品的荧光量子产 率。结果:实验表明不同的取代基对四苯基卟啉及其衍生物荧光强度和荧光峰位移影响较小,但在非极性溶剂 中荧光峰略有红移,并且溶剂影响光敏剂的量子产率,在CHCl3,DMSO中量子产率较高。结论:通过以上实验, 可以从样品中选择出光敏性能较好的光敏剂。
Objective: To study the fluorescence spectra of tetraphenylporphyrine and its fluorescence quantum yields, so as to search for better photosensitizer. Methods: Fluorescence analysis was adopted to test the fluorescence spectra of tetraphenylporphyrine under different conditions, and reference method was used to measure the fluorescence quantum yields. Results: The fluorescence peaks shift to red a little in solvents with small polarity. The fluorescence intensity of the tetraphenylporphine complex with the metal ions is much low. The fluorescence quantum yields of the tetraphenylporphine and its substitutive derivatives had higher values in solvents CHCl 3 and DMSO. Conclusion: Tetraphenylporphine complex might be a better new photosensitizer source.
