Ultrafast excited state relaxation dynamics of branched donor-pi-acceptor chromophore: Evidence of a charge-delocalized state
Article Abstract:
Entire excited state deactivation of monomer 4-N,N-(dimethylamino)-4'-nitrotolane (DMNAT) and trimer, tris-4,4',4"-(4-nitrophenyleethynyl) triphenylamine (T-NPTPA) in different solvents using femtosecond transient absorption measurements is investigated. The results have unambiguously revealed that the charge-delocalized C3 symmetry state is the Franck-Condon (FC) state for trimer in all solvents.

The chromophore of asFP595: A theoretical study
Article Abstract:
The electronic and structural properties of the chromophore of the asCP/asFP595, a newly discovered protein of the (green) fluorescent protein (GFP) family, are investigated. The analysis has shown that the most probable structure of the photoactive moiety in the protein and in water is the one resulting from the GFP-like rather than the alternative cyclization scheme.

Electronic excitations of green fluorescent proteins: modeling solvatochromatic shifts of red fluorescent protein chromophore model compound in aqueous solutions
Article Abstract:
The behavior, structures and electronic excitations of various red fluorescent proteins (RFPs) and green fluorescent proteins (GFPs) are discussed. The analysis reveals that a protein environment is very important while determining the conformation of chromophores in these proteins.
