A donor-acceptor (DA) &pgr;-conjugated polymer with high charge transfer mobility has a plurality of D1kAD1k portions, where k is 1 or 2, D1 is a donor unit having at least one solubilizing side chain, and A is an acceptor unit, and the donor-acceptor (DA) &pgr;-conjugated polymer has a plurality of D2m spacer sequences situated between the D1xAD1x portions, where m is 1 to 6 and D2 is a second donor unit where all atoms of the unit are coplanar in at least one conformation that the unit can assume. The DA &pgr;-conjugated polymer can reflect a blue tinted green, deep green, or yellow tinted green color. The DA &pgr;-conjugated polymers have space-charge limited (SCL) zero field hole mobilities of at least 1×10−6 cm2V−1s−1. |
