Excited-state intramolecular proton transfer from the azomethine group to the nitro group of N-(2-nitrobenzylidene)-3-amino-5-methylpyrazole induced the formation of 2-nitrosobenzamide attended by vivid color change from yellow to reddish brown in the crystal state.
N-(2-硝基苄亚基)-3-氨基-5-甲基吡唑的偶氮甲基亚基到硝基基团的激发态分子内质子转移,在晶体状态下诱导了2-亚硝基苯甲酰胺的形成,并伴有从黄色到红棕色的鲜艳颜色变化。
