Photo-modulated charge transport in single-molecule optoelectronic devices

Abstract

Single-molecule optoelectronic devices have attracted significant attention due to their capability of achieving efficient photon-to-electron conversion and precise modulation of molecular electronic properties at the single-molecule scale, offering new pathways for developing nano-optoelectronic devices and molecular-scale energy conversion systems. With the advancement of characterization technologies and theoretical methodologies, single-molecule optoelectronic devices demonstrate tremendous potential in surpassing the physical limits of conventional devices and enabling customized functionalities at the molecular scale, necessitating a systematic review of current research progress and future challenges. This review systematically summarizes the strategies and technologies used to modulate optoelectronic transport at the single-molecule level, with a particular emphasis on the charge transport mechanisms and potential applications in molecular optoelectronic devices.
