Light-Emitting Multifunctional Polymers for Organic Lasers and Laser Diodes – MELODIE

The first demonstration of electrically-pumped Organic Laser Diode OLD, based on an evaporated single blue emitter layer, has been recently demonstrated (2019). This very important breakthrough will lead to a new class of extremely compact, cheap and flexible lasers with broad industrial applications. In this context, the design of new efficient lasing materials, easily processable and color-tunable, is now highly anticipated. In this project, we propose to developed novel solution processable donor/acceptor polymeric emitters presenting an intramolecular charge transfer ICT, specifically designed to match the requirements of lasing materials under electrical pumping and that can be tuned to emit at different wavelengths throughout the visible spectrum. This extremely relevant and timely project will be based on a multidisciplinary approach, including modelling (TD-DFT) and advanced photophysics to investigate material triplet states that will enable a rational molecular design for high performance laser dyes and to develop for the first time a series of multicolor OLDs.
