A Novel poly {(2,5-diyl thiophene) (2-Thiophenyl Methine)} from the Acid-Catalyzed Polycondensation of thiophene and thiophene-2-carbanaldehyde

Conjugated poly [(thiophene methine) have been synthesized by a simple method: Condensation of thiophene-2-carbaldehyde with thiophene, catalyzed by Maghnite-H+, which is an exchanged montmorillonite sheet silicate with protons to produce Maghnite-H+ non-toxic cationic catalyst, and characterized by...

description Conjugated poly [(thiophene methine) have been synthesized by a simple method: Condensation of thiophene-2-carbaldehyde with thiophene, catalyzed by Maghnite-H+, which is an exchanged montmorillonite sheet silicate with protons to produce Maghnite-H+ non-toxic cationic catalyst, and characterized by FT-IR and UV-Vis. The result reveals that the yield of PTTM increase with time and amount of Mag-H. The results obtained with optical measurements and analyzed by different models, show clearly that our material (PTTM) is a good semi-conductor, when the average gap around 5 eV. The effect of the amount of Mag-H+, and the time of polymer was studied.
