Molecular Engineering of Interlayer Exciton Delocalization in 2D Perovskites

Abstract

In recent years, significant progress has been made in improving the stability, photocurrent efficiency and charge transport properties of 2D hybrid perovskites, making them increasingly relevant for optoelectronic devices. Although these layered systems are typically considered quantum wells due to carrier confinement, an emerging strategy is to generate new perovskite functionalities with -conjugated electroactive cores as spacer molecules, which introduce
