“…The corrugated-2D structures to produce white-light broadband emissions, first reported in 2014, were found to have large structure distortion and strong exciton-lattice coupling with efficient exciton self-trapping [12]. Lowering the dimensionality further to 1D at the molecular level, stronger quantum confinement and exciton-lattice interaction were observed with broadband emissions [13]. In an extreme case, when the metal halides are completely isolated by the organic moieties, 0D structure at the molecular level can be obtained to display the intrinsic properties of individual metal halide species [14].…”

“…This environmentally friendly 1D metal halide hybrid has other features that make them highly attractive for optoelectronic applications, including moisture stability, a long room-temperature PL lifetime, and photoconductive behavior. 1D structures containing transition metal manganese (Mn) have also been studied recently [13,[125][126][127][128]. These Mn-based 1D hybrids were reported to exhibit bright photoluminescence originating from the (t 2g ) 3 (e g ) 2 -(t 2g ) 4 (e g ) 1 electronic transition of Mn 2+ ions with a high quantum yield under UV excitation.…”

Organic-inorganic metal halide hybrids have emerged as new generation functional materials with exceptional structure and property tunability for a variety of applications. Besides the most investigated ABX 3 metal halide perovskites, a variety of hybrids consisting of a wide range of organic cations and metal halide anions have been developed and studied recently. Here, we provide an overview of these new materials possessing various crystallographic structures, including double perovskites, low dimensional hybrids, and other perovskite-related materials. We discuss their syntheses, functional properties, and optoelectronic applications. Challenges and opportunities are then laid out for these hybrid materials beyond perovskites. IMPACT STATEMENTBy choosing appropriate organic cations and metal halide anions, single crystalline ionically bonded hybrid materials can be assembled to possess various structures beyond the well-known ABX 3 perovskite. These hybrid materials exhibit exciting new properties with potential applications in a variety of areas. ARTICLE HISTORY

Over the past decade, lead halide perovskites (LHPs) have emerged as new promising materials in the fields of photovoltaics and light emission due to their facile syntheses and exciting optical properties. The enthusiasm generated by LHPs has inspired research in perovskite-related materials, including the so-called “zero-dimensional cesium lead halides”, which will be the focus of this Perspective. The structure of these materials is formed of disconnected lead halide octahedra that are stabilized by cesium ions. Their optical properties are dominated by optical transitions that are localized within the individual octahedra, hence the title “‘zero-dimensional perovskites”. Controversial results on their physical properties have recently been reported, and the true nature of their photoluminescence is still unclear. In this Perspective, we will take a close look at these materials, both as nanocrystals and as bulk crystals/thin films, discuss the contrasting opinions on their properties, propose potential applications, and provide an outlook on future experiments.

Mechanical exfoliation of 2D materials has triggered an explosive interest in low dimensional material research. We extend this idea to 1D van der-Waals materials. Three 1D semiconductors (SbSeI, SbSI, and SbSBr) with high stability and novel electronic properties are discovered using first principles calculations. Both the dynamical and the thermal stability of these 1D materials are examined. We demonstrate that their nanowire thinner than 7Å can be easily obtained by mechanical exfoliation, hydrothermal method, or sonochemical method. The bulk-to-1D transition results in dramatic changes in band gap, effective mass, and static dielectric constant due to quantum confinement, making 1D SbSeI a highly promising channel material for transistors with gate length shorter than 1 nm. Under small uniaxial strain, these materials are transformed from indirect into direct band gap semiconductors, paving the way for optoelectronic devices and mechanical sensors. Moreover, the thermoelectric performance of these materials is significantly improved over their bulk counterparts. These highly desirable properties render SbSeI, SbSI, and SbSBr promising 1D materials for applications in future microelectronics, optoelectronics, mechanical sensors, and thermoelectrics.
