| 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(H_2TPP)。美国专利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H_2TPP作为VMD片(一种新型非银盐成象体系)的增感剂,未获成功。

| Abstract: | meso-Tetraphenyl-porphyrin (H_2TPP) was first used as an indicator of acid sensitive film composed of vinylidene chloridemethyl acrylate copolymer.The color of H_2TPP-acid sensitive film changes from purplish red to green upon exposure to 254 nm light due to the formation of HCl salt of H_2TTP. HCl is released from acid sensthive film up on UV irradiation. H_2TPP-acid sensitive film showed a better image stability than that with dimethyl yellow because a shang polar compound is formed from IR spectra results. |
