The present work aimed to prepare some compounds for use in pigmented solar cells based on charge transfer (CT) complexation. For this purpose, first, several derivatives of 1,8-naphthalimide and benzanthrone fluorescent dyes were synthesized. Secondly, the synthesized fluorescent dyes were complexed with picric acid (PA) acceptor via CT interaction in methanol solvent at room temperature. Then, the synthesized CT complexes were stoichiometrically, spectroscopically and thermally characterized. The results obtained from CHN elemental analyses and spectrophotometric titrations indicated the formation of CT complexes with a molar ratio of 1:1 between the PA and each dye. The spectroscopic and physical parameters (K-CT, epsilon(max), E-CT, f, mu, R-N, I-P and Delta G degrees), the band gap energy (E-g), and the kinetic-thermodynamic parameters (E*, A, Delta S*, Delta H* and Delta G*) were calculated for each CT product in methanol solvent at room temperature. IR results indicated that the complexation between each dye and PA acceptor occurs through pi -> pi* and proton transfer interactions. (C) 2018 Elsevier B.V. All rights reserved.
