A Review on Organic Nanoparticle-based Optoelectronic Devices: From Synthesis to Applications

Abstract

Over the past decades, organic optoelectronic devices have shown broad application prospects. Due to the solubility property of organic materials, the use of toxic solvent obstacles the device fabrication processing in the air environment. Common approaches such as exploring non-halogenated solvents or side-chain modification do not address the root of the problem. With the increasing attention of the subject of nanoparticles, dispersing organic materials as nanoparticles in non-toxic water/alcohol solvents provides a perfect and universally applicable solution to address the toxicity problem. In addition, the unique properties of nanoparticles can provide new ideas for the optimization and tuning of organic optoelectronic devices. In this review, we present an up-to-date overview of water/alcohol-based organic nanoparticles applied in optoelectronic devices, encompassing the entire journey from nanoparticles to practical applications, partitioned into three vital segments: from organic semiconducting materials to nanoparticles, organic thin films, and finally device applications.
