Description
Paper present the inhibition of excited state proton transfer (ESPT) in 2,2'-pyridylbenzimidazole (PBI) complex by replacing H2O with D2O and NH3as the hydrogen bondedsolvents. The ESPT energy barriers in the S1 electronic states were experimentally examined using resonant two photon ionization and hole-burning spectroscopic methods. The measured ESPT energy barriers of 392 cm-1 in PBI-H2O complex was found to be significantly increased to >800 cm-1 in the PBI-D2O and PBI-NH3 complexes
