摘要：
Two new benzobisimidazole platforms incorporating 7-hydroxyquinoline moieties were synthesized and characterized to explore potential multiple proton transfer processes. Combining experimental analysis with theoretical insights, we investigated the photophysical properties and excited-state proton transfer phenomena within these systems and found that double proton transfer is unlikely to happen. Two new benzobisimidazole platforms incorporating 7-hydroxyquinoline moieties were synthesized and characterized to explore potential multiple proton transfer processes.
