摘要:
A method of synthesis of a new class of push-pull chromophores with vinylquinoxalinone conjugated bridges has been proposed; two isomeric pairs of chromophores with dimethyl aniline donor and dicyanovinyl or tricyanofuran acceptors linked via vinyl-7(6)-quinoxalinon-3-yl or vinyl-7(6)-quinoxalinone-3-vinyl bridges, correspondingly, have been synthesized and systematically investigated. The solvatochromic behavior, thermal stability and electrochemical properties were studied to establish the structure-property relationships. Chromophore 7-DMA-VQ(on)V-TCF exhibits the minimal HOMO-LUMO energy gap (Delta E 0.84 eV) and the highest thermal stability (T-d = 313 degrees C). (C) 2017 Elsevier Ltd. All rights reserved.
