四苯基卟啉变色酸敏片
摘要:
卟啉自由碱通常是紫或紫红色固体,遇酸则变成绿色,对光敏感。人工合成的卟啉最简单的是四苯基卟啉(H2TPP)。美国专利[2]曾将卟啉类化合物作为光氧化成象体系的增感剂。我们试图将H2TPP作为VMD片(一种新型非银盐成象体系)的增感剂,未获成功。

ON THE PHOTOCHROMIC meso-TETRAPHNYL PORPHYRIN ACID SENSITIVE FILM
Abstract:
meso-Tetraphenyl-porphyrin (H2TPP) was first used as an indicator of acid sensitive film composed of vinylidene chloridemethyl acrylate copolymer.The color of H2TPP-acid sensitive film changes from purplish red to green upon exposure to 254 nm light due to the formation of HCl salt of H2TTP. HCl is released from acid sensthive film up on UV irradiation. H2TPP-acid sensitive film showed a better image stability than that with dimethyl yellow because a shang polar compound is formed from IR spectra results.
