  Aggregation induced emissive carbazole-based push pull NLOphores: Synthesis, photophysical properties and DFT studies

  摘要：

  2-Alkoxy-9-methyl-9H-carbazole-3-carbaldehyde based push pull chromophore were efficiently synthesized by a multi-step reaction starting from 9H-carbazole-2-ol. The fluorescence properties of these D-pi-A chromophores were investigated in various solvents of varying polarities and in mixed solvent solutions of DMF and H2O. They exhibited low fluorescent intensity in solution but a high fluorescent intensity in aggregate forms and in their solid state due to the promising aggregation-induced emission enhancement characteristics. These dyes were fully characterized by FT-IR, H-1 NMR and HRMS spectra. The ratio of ground to excited state dipole moment of the novel push pull chromophore were calculated by Bakhshiev and Bilot-Kawski correlations. All the four dyes show more or less twisted intramolecular charge transfer (TILT) characteristics. They show a large first hyperpolarizability value ranging from 189-721 x 10(-3) esu by theoretical method and 73-330 x 10(-30) esu by experimental method. (C) 2015 Elsevier Ltd. All rights reserved.
