Description
Summary:碩士 === 國立臺灣大學 === 化學研究所 === 95 === A four fused-ring system 11-propyl-6H-indolo[2,3-b]quinoline (6HIQ) is strategically designed and synthesized; it possesses a central moiety of 7-azaindole (7AI) and undergoes excited-state double proton transfer (ESDPT). Despite the concerted ESDPT in the 6HIQ dimer, femtosecond dynamics unveils a stepwise ESDPT process in the 6HIQ/7AI heterodimer complex, in which 6HIQ delivers the pyrrolyl proton to 7AI in less than 150 fs, followed by the transfer of pyrrolyl proton from 7AI to the pyridinyl nitrogen of 6HIQ in ~1.5 ± 0.3 ps.
