ABSTRACT:Two novel soluble conjugated polythiophenes, poly [3-(N-hexyl-4-piperidinemethylene)-thiophene] and poly [3-(N-caproyl-4-piperidinemethylene)-thiophene] have been synthesized successfully. Structures of the monomers and the corresponding soluble polymers were elucidated by 1 H NMR, MS, and IR. In addition, the polymers were also characterized by cyclic voltammetry and scanning electron microscopy. Photoluminescence spectra and UV-vis spectra of the two polythiophenes in both solution and solid state were also investigated, and all peaks were bathochromically shifted when they were measured in the solid state. The results of optical and electrochemical measurements indicated that the carbonyl group on the side chain has influence on the electrochemical properties of the conjugated polythiophenes. The electrochemical measurements indicated that the two conjugated polythiophenes may be a promising candidate for the application in polymer photovoltaic cells and field-effect transistors.

“…The C=C and C=O stretching vibrations in the side-chains can be found at 1639 and 1742 cm À1 in Figure 3(b), but the band at 1742 cm À1 disappeared, it is just the difference between polymer P3BRMT and P3BLMT. The sharp and strong absorption band at about 849 cm À1 (C-H out-of-plane vibration), characteristics of 2,3,5-trisubstituted thiophene rings, is in agreement with α-α coupled monomers and it confirms the polymerization [21]. The molar mass of the two polymers were determined by GPC in THF toward polystyrene standards.…”

as an oxidizing agent. In P3BLMT and P3BRMT, substituted piperidine rings are connected with the polythiophene backbone through carbon-carbon double bond. While in the two polythiophenes, the significant difference is the substituent linked to the N-atom of the piperidine effectively. Structures of the monomers and the corresponding soluble polymers were elucidated by 1 H NMR, 13 C NMR, and IR. Average molecular weights have been determined by gel permeation chromatography. Photoluminescence spectra and ultraviolet-visible spectra of the two polythiophenes in both solution and solid states were also investigated, and all peaks were bathochromically shifted when they were measured in the solid state. The results of optical and electrochemical measurements indicate that the carbonyl group on the sidechain has obvious influence on the electrochemical properties of the conjugated polythiophenes. In addition, the polymers were also characterized by cyclic voltammetry and scanning electron microscopy.

Polythiophenes with ester substituents at the 3-position of the thiophene ring were synthesized by ferric chloride oxidative polymerization. The polythiophenes are partially soluble in tetrahydrofuran, and these solutions were used to characterize the polythiophenes using Fourier transform infrared, 1 H NMR, UV-visible and fluorescence spectroscopy, gel permeation chromatography, thermogravimetric analysis, differential scanning calorimetry and cyclic voltammetry. The electrochemical band gap of the polymers is in the range 1.6-2.3 eV. The effect of the various substituents on the fluorescence behaviour was studied in detail. The quinolinyl-moiety-containing polythiophene ester has the highest fluorescence quantum yield. The incorporation of Al 3+ and Zn 2+ ions increases greatly the fluorescence intensity. The electroluminescence properties of the polymers were evaluated with a device configuration of ITO/PEDOT : PSS/polymer/LiF/Al. The polymers show a yellow emission in electroluminescence spectra. The results suggest that the quinoline-containing ester-substituted polythiophene is a promising electronic and optoelectronic material.
