exp3. Color-Tunable Light-Emitting Polymers via the Controlled Oxidation of MEH-PPV

1. Abstract

Color-tunable light-emitting polymers (LEPs) represent a significant advancement in the field of optoelectronic materials, offering versatile applications in displays, lighting, and sensors. This report discusses the controlled oxidation of poly(2-methoxy-5-(2`-ethylhexyloxy)-1,4-phenylene vinylene) (MEH-PPV) as a means to achieve tunable photoluminescence properties. The process of oxidation alters the electronic structure and photophysical properties of the polymer, allowing for precise control over the emission wavelength. By systematically varying the oxidation conditions, including temperature, reaction time, and the concentration of the oxidizing agent, it is possible to tune the color of emitted light. This process involves the transition of the polymer from a neutral state to a more oxidized form, which introduces new electronic states within the bandgap of the polymer. Consequently, the emission spectrum shifts accordingly, enabling emissions across the visibl
