The Synthesis and Characterization of -3,4-Ethylenedioxythiophene Derivatives with Electroactive Features
摘要:
We report the synthesis of conjugated oligomers based on electron withdrawing 3,4-ethylenedioxythiophene (EDOT) in the case of which band gaps are tuned by the insertion of alkylated diphenylamine or phenoxazine/phenothiazine units. The structures and properties of synthesized compounds were characterized by H-1 NMR, C-13 NMR, UV-Vis absorption, and fluorescence spectroscopy as well as electrochemical measurements. The luminescence spectra demonstrate that copolymers are good chromophores. Also the electrical properties confirm the applicability of these novel aryl-based pi-conjugated oligomers for the development of various electrical and electrochemical devices.

The benzothiadiazole – arylene alternating conjugated oligomers have been designed and synthesized via Suzuki coupling reaction. The structures and properties of the conjugated oligomers were characterized by 1HNMR, 13CNMR, UV–vis absorption spectroscopy, photoluminescence (PL) spectroscopy. The luminescent measurements demonstrate that polybenzothiadiazoles are good chromophores able to form thin films by Langmuir-Blodgett (LB) technique, making them suitable for further applications. Also the electrical properties of obtained films confirm the good potential of these novel aryl-based π-conjugated polymers for the development of various electrical and electrochemical solid-state devices.
