四苯基卟啉类光敏剂在醇-酸体系中的光谱性质研究

The Spectra Properties of the Tetraphenylporphine Substituents in the Solution of Acid with Enthanol

研究了四苯基卟啉类光敏剂在醇-酸体系中的光谱性质,以及在此体系中浓度、酸度、表面活性剂等因素对其光谱性质的影响,首次发现在醇-酸体系中四苯基卟啉类光敏剂的光谱性质发生改变,靠近红外区均有中强度吸收,它们在可见光波长的激发下能产生在近红外区的荧光峰,与硫酸比较而言,盐酸配制的醇-酸体系优于硫酸体系.醇与酸的配比最好选择10:1,酸的最佳浓度选择1mol·L-1.优选出四-(p-甲基苯基)卟啉和四-(p-甲氧基苯基)卟啉这两种光敏活性物质.

The spectrum of the tetraphenylporphine substituents and its derivatives were studied in the solution of acid with enthanol. It was found that the solubility of the H2(p-MeO)TPP and H2TTP increased in this solution, their absorption and fluorescence spectra differ from those in the organic solvents,HCl is better than H2SO4, the best proportion of enthanol to HCl(1 mol·L-1) is 10 : 1, Their absorption and fluorescence peak is close to near infrared.we found H2(p-MeO)TPP and H2TTP are two better new photosentizes.
