Abstract
The present invention relates to new semiconductive oligomers and polymers, a process for their manufacture and their use in thin film electronic and optical devices, such as organic light emitting diodes (OLED) and photovoltaic devices, eg. solar cells and photodetectors.
Claims24
An oligomer or polymer comprising an optionally substituted first repeat unit of formula (Ir):
- wherein R1, R2, R3 and R4, which may be the same or different, are independently selected from hydrogen or a substituent and two or more of R1, R2, R3 and R4 may be linked to form a ring.
An optionally substituted monomer of formula (Im):
- wherein R1, R2, R3 and R4, which may be the same or different, are independently selected from hydrogen or a substituent and two or more of R1, R2, R3 and R4 may be linked to form a ring;
- and each P represents a polymerisable group.
A method of forming an optionally substituted compound of formula (I):
- comprising the step of eliminating LG-H from an optionally substituted compound of formula (Ip):
- wherein each LG is the same or different and represents a leaving group.
