AN IMPROVED ROOM TEMPERATURE CHEMICAL VAPOUR DEPOSITION PROCESS FOR THE DEPOSITION OF POLY (PHENYLENE-VINYLENE) IN THE MANUFACTURE OF ORGANIC BASED ELECTRONIC DEVICES

摘要

An improved process for the manufacture of organic semiconducting polymer Poly (phenylenevinylene) for use in electronic devices such as light emitting diodes, thin film transistors etc., whereby it would be possible to obtain such semiconducting polymer on a wide variety of substrates and favour cost effective manufacture of semi conducting polymers. In particular, the invention relates to manufacture of the semiconducting polymer Poly(phenylenevinylene) at room temperature using ultraviolet light. Importantly, the improved process can be carried out at lower temperature and will thus favour obtaining of the semi conducting polymer from cost effective sources and enable manufacture of such cost effective polymers. Moreover the improved process would favour use of roll to roll processing in the manufacturing of abovesaid semiconducting polymers and further enable band-gap tuning of Poly (phenylenevinylene) via photoinduced dehydrohalogenation. Additionally the improved process is adapted to pattern Poly (phenylenevinylene) using a lift-off process.
