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.
Two porphyrin derivatives, TPP-AQ and TPP-PD, were synthesized by Schiffbase reaction.The properties of TPP-AQ and TPP-PD were studied by cyclic voltammetry, UV-Vis absorption spectra, fluorescence spectra and theoretical calculations. -PD oxidation potential were E1 / 2 = 1.07,1.30V and 1.21,1.36V respectively. Compared with TPP-PD, the two redox potentials of TPP-AQ negatively shifted. The TPP-AQ and TPP-PD The maximum UV-visible absorption peaks are at 441 and 431 nm, respectively, and the absorption wavelength of TPP-AQ has a certain degree of red-shift compared with that of TPP-PD. The theoretical calculation shows that this is due to the better conjugation degree of TPP-AQ than TPP- The fluorescence main emission peaks of -AQ and TPP-PD are at 657 and 656 nm, respectively. The full width at half maximum is 30 and 27 nm, respectively.
