Polymer Blends with High Charge Mobilities and Enhanced Solution-Processability
Researchers at Purdue University have developed a two-step approach to reveal the nature of the connections between crystalline aggregates in polymer thin films. The first step involves the study of a semiconducting polymer with intentionally placed conjugation-break spacers along the polymer backbone. The second step brings in a fully conjugated polymer that is blended into the non-conjugated polymer matrix as tie chains to bridge crystalline aggregates. The findings elucidate the role of conjugated tie chains for efficient charge transport and enable a new design principle to take advantage of complementary binary polymer blends to obtain high mobility electronic materials with enhanced solution-processability for future organic electronics.
