摘要：

Two pyrazoline core fluorescent materials were designed, synthesized and characterized by various approaches. The synthesized materials were confirmed by standard H-1 NMR and FT-IR techniques. Porous like morphologies were found from SEM analysis and the thermal stability of the materials analyzed with TGA-DSC analysis. Emission properties, quantum yield, lifetime and bandgap energy of the materials have also been studied. Solvent effect of absorption and emission spectral results indicated that the wavelength was red-shifted to increase the solvent polarity. The semiconducting nature was studied by UV-visible spectra, cyclic voltammetry analysis and theoretical calculation. I-V characteristic analysis was used to determine turn-on voltage of the materials for optoelectronics. (C) 2015 Elsevier B.V. All rights reserved.
