Solid-state Nuclear Magnetic Resonance (SSNMR) spectroscopy provides an unparalleled means of probing these interactions at the atomic level by directly sensing local electronic environments, independent of long-range order. This review surveys recent advances (approximately since 2020) in SSNMR methodologies for detecting, characterizing, and quantifying weak interactions in molecular solids. Particular emphasis is placed on developments in high-field and ultrafast magic-angle spinning (MAS) instrumentation, as well as novel pulse sequences that enhance access to key nuclei involved in non-covalent bonding. SSNMR observables, such as chemical shifts, dipolar and <em>J</em> couplings, quadrupolar parameters, and relaxation rates, are shown to provide quantitative insight into the interaction strength, geometry, and dynamics of hydrogen-bonded, π-stacked, and σ-hole-bonded systems. The review also discusses the synergistic integration of SSNMR with diffraction (single-crystal and powder X-ray diffraction, electron diffraction) and computational methods (Crystal Structure Prediction, DFT calculations, molecular dynamics simulations, machine learning models), yielding a multidimensional framework for elucidating structure–property relationships in both crystalline and disordered materials. Special attention is devoted to complex environments such as multicomponent crystals, host–guest assemblies, and amorphous dispersions.

A variety of pollutants have grown more persistent in aquatic environments. The inappropriate use of dyes and antibiotics, as well as their inadequate digestion in organisms, results in their discharge into aquatic habitats, which has harmed human health. Therefore, effective removal of textiles and pharmaceuticals, especially dyes and antibiotics, from wastewater and polluted water bodies is of significant interest to research communities across the world. Besides, the depletion of fossil fuels increases the demand for renewable energy sources. Since solar energy is the most abundant and endless energy source, it provides an environmentally friendly alternative to fossil fuels. Metal-organic frameworks (MOFs), which are porous crystalline hybrid materials formed by the linkage of metal centers (clusters) and organic linkers (organic ligands), have been identified as a highly active research domain for more than a decade due to their wide range of applications as photocatalytic and photovoltaic. In the present research domain, the research community has been drawn to emerging MOFs by their distinctive properties, which include a large surface area, controllable morphologies, tunable porosities, layer-by-layer design, high-quality crystalline products, outstanding inorganic-organic nature, and incredible diversity in functionalities. In this review, the latest developments in the use of MOFs and their derivatives in a variety of solar cell technologies, such as dye-sensitized, perovskite, and organic solar cells, are methodically described. These MOF-based photovoltaic systems have shown remarkable potential for enhancing sunlight-to-electricity conversion efficiency and improving stability. In addition, the utilization of MOFs and their derivatives as photocatalysts is a highly effective approach for breaking down dye and antibiotic residues in water. Key improvements and modifications, such as stronger interfacial contact, enhanced light harvesting, and improved charge separation, have been emphasized to develop potent photocatalysts that significantly enhance the removal of dyes and antibiotics. The environmental factors influencing photocatalytic degradation activity, such as photocatalyst concentration, pollutant concentration, solution pH, light intensity, reaction temperature, Fenton reagent, and scavengers, were thoroughly discussed, assisting in the design of an ideal photoreactor with high photocatalytic efficiency and a cost-effective process.

This review systematically outlines construction strategies for dual-emission COF-based ratiometric sensors, such as intrinsic backbone dual-emission, doping-induced dual-emission, and hybrid/heterostructure-induced dual-emission. For each approach, advantages, limitations, and development directions are discussed. Key structural factors (e.g. topology, π–π stacking, donor–acceptor motifs, pore environment, and crystallinity) and their roles in integrating luminescent units are discussed to explain how they collectively influence dual-emission performance and stability. Common construction challenges and corresponding mitigation strategies are also summarized to enhance sensor reliability and efficiency. The review further elaborates on relevant sensing mechanisms, including excited-state intramolecular proton transfer (ESIPT) and Förster resonance energy transfer (FRET), as well as summarizes the interrelationships of construction strategy-response mode-sensing mechanism.
