Controlling the adiabacity of electron-transfer reactions using nematic liquid-crystal solvents
Article Abstract:
Transient absorption studies of intramolecular charge separation and recombination within an electron donor-acceptor molecule dissolved in nematic liquid-crystal (LC) solvents are reported. The molecule consisted of a 4-(N-pyrrolidinyl)naphthalene 1,8-imide electron donor (PyrNI) covalently attached to a pyromellitimide acceptor (PI). Transient absorption studies of the PyrNI-PI complex, which was dissolved in N-(4-methoxybenzylidene)-4butylaniline (MBBA), show the solvation dynamics of charge separation charge recombination in MBBA to be highly conventional.

Unusually high fluorescence enhancement of some 1,8-Naphthalimide derivatives induced by transition metal salts
Article Abstract:
Fluorescence behavior of some structurally simple multicomponent systems has been studied in the presence and in absence of the transition metal salts. Preferential solvation of the fluorophore component of the multicomponent system by the water molecules of the hydrated salts of the metals has been identified as one possible origin of the unusually high fluorescence enhancement (FE) shown by some of the systems.
