Excited-State Decay Paths in Tetraphenylethene Derivatives
The photophysical properties of tetraphenylethene (TPE) compounds may differ widely depending on the substitution pattern, for example, with regard to the fluorescence quantum yield ϕf and the propensity to exhibit aggregation-induced emission (AIE). We report combined electronic structure calculations and nonadiabatic dynamics simulations to study the excited-state decay mechanisms of two TPE ...

Z. Naturforsch. 51 b, 1067-1071 (1996); received March 8, 1996 Myochrysin, Auranotin. Gold(I) Complexes, Photochemistry, Luminescence Myochrysin (sodium aurothiomalate hydrate) and auranofin [2,3.4,6-tetra-O-acetyl-l-thio-ßD-glucopyranosato-S)(triethylphospine)gold(I)] are luminescent in the solid state and in ethanol glasses at 77 K (myochrysin: Amax = 600 nm; auranofin: 618 nm). Aqueous myoch...
متن کاملExcited state properties of aryl carotenoids.
Excited-state properties of aryl carotenoids, important components of light harvesting antennae of green sulfur bacteria, have been studied by femtosecond transient absorption spectroscopy. To explore effects of the conjugated aryl group, we have studied a series of aryl carotenoids with conjugated phi-ring, chlorobactene, beta-isorenieratene and isorenieratene, and compared them with their non...
متن کاملTuning the excited-state dynamics of GFP-inspired imidazolone derivatives.
The excited-state dynamics of five derivatives of the GFP-chromophore, which differ by the position and nature of their substituents, has been investigated in solvents of various viscosity and polarity and in rigid media using femtosecond-resolved spectroscopy. In polar solvents of low viscosity, like acetonitrile or methanol, the fluorescence decays of all compounds are multiexponential, with ...
متن کاملInfluence of excited state aromaticity in the lowest excited singlet states of fulvene derivatives.
The absorption spectra and excited state dipole moments of four differently substituted fulvenes have been investigated both experimentally and computationally. The results reveal that the excited state dipole moment of fulvenes reverses in the first excited singlet state when compared to the ground state. The oppositely polarized electron density distributions, which dominate the ground state ...
