Abstract A new series of platinum (II)-acetylide polymers P1, P2, P3 containing thiophene- triarylamine chromophores of different dimensions were synthesized and their electronic band structures, field-effect charge transport, and application in bulk heterojunction solar cells were evaluated. These materials are soluble in polar organic solvents and show strong absorptions in the solar spectra (with the highest absorption coefficient of 1.59× 10 5 cm− ...
