摘要

New types of asymmetrical photochromic diarylethene derivatives having a pyrazole unit, namely 1-[1, 3, 5-trimethyl-1-pyrazol-4-yl], 2-[2-methyl-5-(4-methoxylphenyl)-1-thien-3-yl] perfluorocyclopentene (1a), 1-[1, 3, 5-trimethylpyrazol-4-yl], 2-[2-methyl-5-(3- methoxylphenyl)-1-thien-3-yl] perfluorocyclopentene (2a), 1-[1, 3, 5-trimethyl-pyrazol-4-yl], 2- [2-methyl-5-(2-methoxylphenyl)-1-thien-3-yl] perfluorocyclopentene (3a), and 1-[1, 3, 5- ...
