Optical and structural proprieties of the new triblock copolymer (A-B-C) based on p-terphenyl, PVK and MEH-PPV for organic electronics: Experimental and theoretical study

Abstract

A new cross-linked triblock copolymer has been elaborated. The optical properties have demonstrated that the resulting material presents original properties compared to the pristine homopolymers. In fact, the optical absorption of the A-B-C copolymer overlapped all the ultraviolet (UV) and visible domain. Furthermore, combined with experimental analyses, DFT and TD-DFT calculations have been used to predict the most probable appropriate model structure of the triblock copolymer. So, the electronic properties of the selected model structure have been computed. All the obtained results support that this new copolymer is usable as an active layer in the optoelectronic fields due to its original properties.
