摘要(Abstract)：

目的 :将四苯基卟啉及其衍生物作为研究对象 ,测定其电子吸收光谱 ,从而筛选出较好的光敏剂。方法 :采用紫外可见分析法测定不同条件下的吸收光谱。结果 :实验表明极性不同的各类溶剂对四苯基卟啉的光谱性质影响并不明显 ,但不同结构的四苯基卟啉化合物的光谱性质有所不同。结论 :从测定样品中可以优选出 2种电子吸收光谱靠近红光区的光敏剂。
Objective: To study the electronic spectra of tetraphenylporphyrine, and, so as to screen better photosensitive agents. Methods: The UV-VIS detect method was adopted to test the spectra of tetraphenylporphyrine and its substitutive derivatives under different conditions. Results: It was found that the tetraphenylporphyrine and its substitutive derivatives exist as monomer in organic solvents with different polarity, but differences were found among electronic spectra of compounds with different structure. Conclusion: At least, 2 kinds of better photosensitive agents could be screened out from the compounds studied.
