An easily prepared phosgene probe, 5′-amino-2-(2′-hydroxyphenyl)benzimidazole (P1), is designed and studied. Based on ESIPT mechanism, P1 exhibits ratiometric, sensitive and selective detection of phosgene both in solution and gas phase.
一种易于制备的光气探针,5'-氨基-2-(2'-羟基苯基)苯并咪唑(P1),已被设计并研究。基于ESIPT机制,P1在溶液和气相中均表现出光气的比例、敏感和选择性检测。
