  • Title: NLOphoric Carbazole-Containing Push-Pull Extended Styryl Chromophores: Study of Photophysical Properties by Solvatochromic and DFT Method.
    Author: Telore RD, Sekar N.
    Journal: J Fluoresc; 2016 Jul; 26(4):1261-70. PubMed ID: 27139909.
    Abstract:
    Carbazole based extended Donor-π-Acceptor styryl dyes with intramolecular charge transfer characteristics were examined for their linear and nonlinear optical properties using solvatochromism, shifts in emission and density functional theory computations. All the extended styryls demonstrated positive solvatochromism. The extended styryl dyes showed largely improved photophysical properties and large Stokes shifts. The donor-acceptor interactions of the extended styryls were investigated by using generalized Mulliken-Hush method. Oscillator strengths and transition state dipole moments have been studied to understand charge transfer within the molecules. The nonlinear optical properties of the extended styryl were investigated by solvatochromic and density functional theory method.
