Photophysical properties of ,4-alkyl- and 7-alkoxycoumarin derivatives. absorption and emission spectra, fluorescence quantum yield and decay time
TL;DR: In this article, 4-Alkyl- and 7-alkoxy coumarin derivatives have been investigated for their spectroscopic properties in three different solvents, and the changes observed for the rates of radiative transitions and also for the positions of the absorption and emission maxima can be explained by changes in the molecular electronic transition moment caused by the weak donation potential of the substituents.

Triplet (T1) state and radical cation resonance Raman investigation of biphenyl derivatives
G. Buntinx,O. Poizat +1 more
TL;DR: In this article, a detailed discussion of the resonance Raman activity and enhancement is given based on simple molecular orbital considerations, which confirms the planar, quinoidal character of the triplet and radical cation structures.

The electronic structure of 4-(N,N-dimethylamino)-4′-cyano-biphenyl and its planar and twisted model compounds
Michael Maus,Wolfgang Rettig +1 more
TL;DR: In this paper, the electronic structure of 4-(N,N-dimethylamino)-4′-cyano-biphenyl and its planar fluorene and twisted 2,6-dimethyl-substituted model compounds is analyzed by experimental means of UV/VIS absorption spectroscopy including linear dichroic and derivative spectra.

van der Waals binding energies and intermolecular vibrations of carbazole⋅R (R=Ne, Ar, Kr, Xe)
TL;DR: In this paper, mass-selective ground-state vibrational spectra of jet-cooled carbazole van der Waals complexes were obtained by populating groundstate intra and intermolecular levels via stimulated emission pumping, followed by time delayed resonant two-photon ionization of the vibrationally hot complex.

Bright, Red Single-Molecule Emitters: Synthesis and Properties of Environmentally Sensitive Dicyanomethylenedihydrofuran (DCDHF) Fluorophores with Bisaromatic Conjugation
TL;DR: Photophysical studies demonstrate that these DCDHF dye materials are strong single-molecule emitters and the total number of detected photons per molecule is among the highest thus far for this family of fluorophores.
