利用Schiff base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, 1.30 V和1.21, 1.36 V, 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431 nm, 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656 nm, 半峰宽分别为30和27 nm, 有较好的红光色纯度.

关键词: 卟啉, 循环伏安, 荧光, 密度泛函

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.

Key words: porphyrin, cyclic voltammogram, fluorescence, density functional theory
