Interfacial engineering has long been a vital means of improving thin-film device performance, especially for organic electronics, perovskites, and hybrid devices. It greatly facilitates the fabrication performance solution-processed devices, including field effect transistors (OFETs), solar cells (OSCs), perovskite (PVSCs), light-emitting diodes (OLEDs). However, due to limitation traditional interfacial materials, further progress these devices is hampered particularly in terms stability, flexibility, sensitivity. The deadlock gradually broken through development self-assembled monolayers (SAMs), which possess distinct benefits transparency, diversity, sensitivity, selectivity, surface passivation ability.
