ABSTRACT
The influence of hydrogen bonding (HB) and protonation on an intramolecular charge transfer (ICT) compound, such as N,N-dimethyl-4-(phenylimino-methyl)-aniline (NMe2-4PmA) in the ground and excited state with two protic solvents 2,2,2-trifluoroethanol (TFE) and 2,2,2-trichloroethanol (TCE) is investigated. Mono HB and mono protonation complexes with TFE and TCE both in the ground state as well as in the excited state are all identified. TCE shows stronger protonation as well as hydrogen bonding ability in the ground state of NMe2-4PmA. In the excited state both TCE and TFE show similar behavior in the hydrogen bonding and protonation ability.
Keywords:
Hydrogen Bonding, Intramolecular Charge Transfer (ICT), Protonation
