中文摘要：

利用Schiffbase反应合成了两个卟啉衍生物TPP-AQ,TPP-PD.通过循环伏安、紫外可见吸收光谱、荧光光谱及理论计算等对其物性进行了研究.结果显示：TPP-AQ,TPP-PD氧化电位分别为E1/2=1.07,1.30V和1.21,1.36V,与TPP-PD相比,TPP-AQ的两个氧化还原电位都发生了负移;TPP-AQ与TPP-PD的最大紫外可见吸收峰分别在441和431nm,TPP-AQ的吸收波长较TPP-PD有一定程度的红移,通过理论计算可知这是由于TPP-AQ共轭程度优于TPP-PD导致的.TPP-AQ和TPP-PD的荧光主发射峰分别在657和656nm,半峰宽分别为30和27nm,有较好的红光色纯度.

英文摘要：

Two porphyrin derivatives TPP-AQ and TPP-PD were synthesized and characterized.The physical properties of these two molecules were studied by cyclic voltammetry,ultraviolet visible spectra,fluorescence spectra and theoretical calculations.The redox potentials of TPP-AQ and TPP-PD are 1.07,1.30 V and 1.21,1.36 V,respectively.The redox potentials of TPP-AQ are negative-shifted compared with those of TPP-PD.The maximum absorptions of TPP-AQ and TPP-PD are 441 and 431 nm,respectively.The maximum absorption of TPP-AQ was red-shifted compared with that of TPP-PD due to that the conjugated effect of TPP-AQ is greater than that of TPP-PD based on the results of theoretical calculations.The red fluorescence peaks of TPP-AQ and TPP-PD are 657 and 656 nm,and the full widths at half-maximum of TPP-AQ and TPP-PD are 30 and 27 nm.
