Abstract:Soluble polymer LCPT, which is a ladder conjugated copolymer of Perylene-3,4,9,10-tetracarboxylic acid diimides (PDI) and thieno[3,2-b] thiophene, was designed on the basis of highly efficient model reaction. Target polymer LCPT was quantitatively obtained by illumination of SCPT with the sunlight in the presence of catalytic amount I2 in boiling toluene. Serious twist make electronic communication between perylene core and thieno[3,2-b]thiophene core difficult and lead to different frontier molecular orbitals. LCPT shows much better thermal stability than SCPT, and the 5% weight loss temperature of LCPT is 60°C higher than that of SCPT. LCPT, with a planar large conjugated system, exhibits strong electron accepting ability, broad absorption, strong fluorescence, and excellent thermal stability.
