Controllable synthesis and heterogeneous tailoring of 1D perovskites, emerging properties and applications

Abstract

One-dimensional perovskites possess unique photoelectric properties that distinguish them from other perovskite types, making them a focal point in photoelectric research. In recent years, there has been a significant surge in interest surrounding the synthesis and application of one-dimensional anisotropic perovskites, spurred by advancements in synthesis techniques and notable breakthroughs in novel methodologies and application properties. This article provides a comprehensive review of the progress made in research on one-dimensional anisotropic perovskites, detailing the synthesis mechanisms and potential pathways for performance enhancement in various applications. We highlight the crucial role of controllable synthesis and heterogeneous effect in tailoring perovskite properties to boost application efficacy. Initially, this review examines the primary synthesis methods and mechanisms for creating heterogeneously induced one-dimensional anisotropic perovskites, categorizing them into two main approaches: the classical wet chemical synthesis, which utilizes selective ligands, and the ligand-free, substrate-assisted method. The precision in controllable synthesis is essential for fabricating heterogeneous structures, where the synthesized precursor, shape, and surface ligand significantly influence the interfacial strength of the heterogenic interface. We also discuss the key features that must be improved for high-performance applications, exploring how heterogeneous effects can enhance performance and drive the development of heterogeneous devices in various applications, such as photodetectors, solar cells, light-emitting diodes, and photocatalysis. Conclusively, by highlighting the emerging potential and promising opportunities offered by strategic heterogeneous construction, we forecast a dynamic and transformative future for their production and application landscapes.
