Abstract
Organic Field Effect Transistor (OFET), an Organic Light Emitting Diode (OLED), an and an Organic Photovoltaic Cell (OPC) including as active material a congugated oligomeric or polymeric 2,7-carbazolenevinylene derivative described by the formula (I) or (II): Such OFETs, OLEDs and OPCs have improved devices properties and efficiencies.
Claims21
