Perovskites are bringing revolutionization in a various fields due to their exceptional properties and crystalline structure. Most specifically, halide perovskites (HPs), lead-free halide perovskites (LFHPs), and halide perovskite quantum dots (HPs QDs) are becoming hotspots due to their unique optoelectronic properties, low cost, and simple processing. HPs QDs, in particular, have excellent photovoltaic and optoelectronic applications because of their tunable emission, high photoluminescence quantum yield (PLQY), effective charge separation, and low cost. However, practical applications of the HPs QDs family have some limitations such as degradation, instability, and deep trap states within the bandgap, structural inflexibility, scalability, inconsistent reproducibility, and environmental concerns, which can be covered by encapsulating HPs QDs into porous materials like metal-organic frameworks (MOFs) or covalent-organic frameworks (COFs) that offer protection, prevention of aggregation, tunable optical properties, flexibility in structure, enhanced biocompatibility, improved stability under harsh conditions, consistency in production quality, and efficient charge separation. These advantages of MOFs-COFs help HPs QDs harness their full potential for various applications. This review mainly consists of three parts. The first portion discusses the perovskites, halide perovskites, lead-free perovskites, and halide perovskite quantum dots. In the second portion, we explore MOFs and COFs. In the third portion, particular emphasis is given to a thorough evaluation of the development of HPs QDs@MOFs-COFs based materials for comprehensive investigations for next-generation materials intended for diverse technological applications, such as CO conversion, pollutant degradation, hydrogen generation, batteries, gas sensing, and solar cells. Finally, this review will open a new gateway for the synthesis of perovskite-based quantum dots.
钙钛矿因其优异的性能和晶体结构正在给各个领域带来变革。最特别的是，卤化物钙钛矿（HPs）、无铅卤化物钙钛矿（LFHPs）和卤化物钙钛矿量子点（HPs QDs）因其独特的光电性能、低成本和简单的加工工艺而成为研究热点。特别是HPs QDs，由于其发射可调、高光致发光量子产率（PLQY）、有效的电荷分离和低成本，具有出色的光伏和光电应用。然而，HPs QDs家族的实际应用存在一些局限性，如降解、不稳定性、带隙内的深陷阱态、结构缺乏灵活性、可扩展性、再现性不一致以及环境问题，将HPs QDs封装到金属有机框架（MOFs）或共价有机框架（COFs）等多孔材料中可以解决这些问题，这些多孔材料提供保护、防止聚集、可调光学性能、结构灵活性、增强的生物相容性、在苛刻条件下提高稳定性、生产质量的一致性以及有效的电荷分离。MOFs - COFs的这些优点有助于HPs QDs充分发挥其在各种应用中的潜力。本综述主要由三部分组成。第一部分讨论了钙钛矿、卤化物钙钛矿、无铅钙钛矿和卤化物钙钛矿量子点。在第二部分中，我们探讨了MOFs和COFs。在第三部分中，特别强调了对基于HPs QDs@MOFs - COFs的材料的发展进行全面评估，以便对用于各种技术应用（如CO转化、污染物降解、制氢、电池、气体传感和太阳能电池）的下一代材料进行综合研究。最后，本综述将为基于钙钛矿的量子点的合成开辟新的途径。
