Perovskites are bringing revolutionization in a various fields due to their exceptional properties and crystalline structure. Most specifically, halide perovskites (HPs), lead-free (LFHPs), perovskite quantum dots (HPs QDs) becoming hotspots unique optoelectronic properties, low cost, simple processing. HPs QDs, particular, have excellent photovoltaic applications because of tunable emission, high photoluminescence yield (PLQY), effective charge separation, cost. However, practical the QDs family some limitations such as degradation, instability, deep trap states within bandgap, structural inflexibility, scalability, inconsistent reproducibility, environmental concerns, which can be covered by encapsulating into porous materials like metal–organic frameworks (MOFs) or covalent–organic (COFs) that offer protection, prevention aggregation, optical flexibility structure, enhanced biocompatibility, improved stability under harsh conditions, consistency production quality, efficient separation. These advantages MOFs-COFs help harness full potential for applications. This review mainly consists three parts. The first portion discusses perovskites, dots. In second portion, we explore MOFs COFs. third particular emphasis is given thorough evaluation development QDs@MOFs-COFs based comprehensive investigations next-generation intended diverse technological applications, CO2 conversion, pollutant hydrogen generation, batteries, gas sensing, solar cells.
