ABSTRACT:
The invention discloses soluble polythiophene derivatives containing highly coplanar repeating units. The coplanar characteristic of side chain conjugated thiophene units improves the degree of the intramolecular conjugation and intermolecular π-π interaction. The polythiophene derivative exhibits good carrier mobility and is suitable for use in photo-electronic device such as organic thin film transistors (OTFT), organic light-emitting diodes (OLEDs), and organic solar cells (OSCs).
