“…The coordination of pyridine groups with the Eu ions offered much better fluorescence when it interacted with fluoride ions. This could help to have the detection limit of 1.6××10 −9 M for the fluoride ions . In another study, Schiff base complex was immobilized over salicylidene functionalized SBA‐15 materials which were later employed as fluorescent chemosensors and showed a great promise for the selective detection of even a trace amount of Zn ions .…”

Organo‐functionalized materials with porous structure offer unique adsorption, catalytic and sensing properties. These unique properties make them available for various applications, including catalysis, CO2 capture and utilization, and drug delivery. The properties and the performance of these unique materials can be altered with suitable modifications on their surface. In this review, we summarize the recent advances in the preparation and applications of organo‐functionalized porous materials with different structures. Initially, a brief historical overview of functionalized porous materials is presented, and the subsequent sections discuss the recent developments and applications of various functional porous materials. In particular, the focus is given on the various methods used for the preparation of organo‐functionalized materials and their important roles in the heterogenization of homogeneous catalysts. A special emphasis is also given on the applications of these functionalized porous materials for catalysis, CO2 capture and drug delivery.

“…As shown in Figure 6, it can be seen that, after ultraviolet radiation, the fluorescence of wood is enhanced, which is perhaps due to the fact that, after a long period of radiation exposure, the silane undergoes further hydrolysis and condensation reactions, leading to the formation of an Si-O network structure, which will increase the rigidity of the ligand and reduce the energy loss by non-radiative deactivation [33]. On the contrary, the condensation reaction of organic-inorganic hybrid coatings change the coordination environment of Eu 3+ , which could be reflected by the ratio of 5 D 0 → 7 F 2 (614 nm) transition to 5 D 0 → 7 F 1 (590 nm) transition [34][35][36]. The larger ratio of 5 D 0 → 7 F 2 transition to 5 D 0 → 7 F 1 means that the chemical environment symmetry around the Eu 3+ ion is decreased [37,38].…”

Environmentally friendly protection coatings have obtained increasing attention for their use in wooden materials, which can be destroyed easily when exposed to outdoor environments. A series of silane sol coatings coordinated with Eu3+ was prepared by hydrolyzing silane compounds. The obtained luminescent coating with three-dimensional net structure showed excellent optical, anti-ultraviolet aging, and thermal stability. The hybrid silane-modified compound coating was well-distributed on the wood by Si–O bonds to prevent its removal. The compound coating could stave off the decomposition of wood by converting ultraviolet light into red light and a charring action can endow the wood with thermal stability at high temperature, demonstrating the improvement of fire resistance and radiation residence following prolonged exposure to ultraviolet light, proving its excellent anti-ultraviolet aging properties.

The recognition and detection of trace fluoride ions in vivo and vitro have attracted great attention in recent years. More and more new fluorescent probes (FP) for fluoride ion detection have been designed and synthesized due to their advantages, such as high sensitivity, good selectivity and convenient operation. According to the different structural features and recognition mechanism, fluoride ion FP can be classified into two categories as deprotonation and reaction type. The new progress especially in recent three years on their molecular design, synthesis and application is reviewed on the viewpoint of green chemistry. The future trend of fluoride ion FP is also prospected.
