Molecularly Regulated Dynamic Interfaces in 3D/2D Perovskites Enabled by Functional Pyridinium Ionic Liquids

open access: yesSmall, EarlyView.
1‐butyl‐4‐methylpyridinium tetrafluoroborate (BMPyBF4) interacts with excess PbI2 during film formation, driving the formation of a low‐dimensional perovskite phase and enabling the self‐organization of a 3D/2D interfacial structure. This molecularly regulated interface suppresses defect‐mediated recombination and facilitates interfacial charge ...

Crystallinity Effects on Near‐Infrared Photoresponse in Y6‐Based Organic Phototransistors

open access: yesSmall, EarlyView.
Solution‐processed Y6 thin films are investigated as active layers of organic field‐effect transistors and as near‐infrared photodetectors. Enhanced crystallinity in Y6 films induced by thermal annealing leads to improved charge transport and pronounced photoresponsivity.
