A Novel Poly{(2,5-diyl furan)‎ (benzylidene)‎} : A New Synthetic Approach and Electronic Properties

الملخص EN

A new conjugated aromatic poly[(furan-2, 5-diyl)-co-(benzylidene)] has been prepared by polycondensation of benzaldehyde and furan catalyzed by Maghnite-H+.

Maghnite-H+ is a montmorillonite sheet silicate clay, which exchanged with protons.

These polymers can be dissolved in high polar solvents such as DMSO, DMF, THF, or CHCl3 A kind of band-gap conjugated poly[(furan-2, 5-diyl)-co-(benzylidene)] has been synthesized by a simple method and characterized by 1HNMR, 13CNMR, FT-IR, and UV-Vis.

The result reveals that the band-gap of the PFB conjugated polymer has an optical band gap of 2.2 eV.
