“…In the case of the cured ADDPP‐OH–EP composites, phosphorus was more reserved in the exterior char layer than in the interior char layer; this indicated an enrichment of phosphorus on the surface of the char layer. During burning, the phosphorus in the diazaphosphorinane ring may have been converted into phosphoric acid, and this may have promoted the degradation of EP and thus facilitated the formation of a phosphorus‐rich carbonaceous layer . In addition, the content of N in the interior char layer was much higher than that in the exterior char layer.…”

A novel PCN bond containing azaphosphorine, 5‐(4‐hydroxy)anilinomethyl‐1,3‐di(4‐hydroxy)phenyl‐1,3,5‐diazaphosphorinane (ADDPP‐OH), which could be used as both a cocuring agent and a flame‐retarding agent for epoxy resins (EPs), was synthesized from tetrakis(hydroxymethyl)phosphonium sulfate and characterized by FTIR, 1H‐NMR, 13C‐NMR, 31P‐NMR, and so on. Compared with the pure EP, the ADDPP‐OH–EP composites showed increased decomposition temperatures and char yields. When the content of ADDPP‐OH was 10 wt %, the cured EP composite possessed a limiting oxygen index value of 33.7% and passed the V‐0 rating of the UL‐94 test. The mechanical properties of the ADDPP‐OH–EP composites was improved because of the increased crosslinking density. In addition, the morphology of the residual char indicated an intumescent and multiporous structure in the inner space and a compact and continual appearance in the outer layer; this was important in preventing the materials from burning further. © 2017 Wiley Periodicals, Inc.

“…There are two methods for the synthesis of oxime-ethers [21,22]. In the present study, we have synthesized a novel series of coumarin-oxime ethers (14-25) via condensation reaction of 3-acetyl coumarin (1) and o-substituted benzylhydroxylamines (2-13) in PPTS/DCM (pyridinium p-toluenesulfonate/ dichloromethane) at reflux temperature in a single step shown in Scheme-I.…”

“…[67] Moreover, the size and shape of the co-catalysts also affect the H 2 evolution activity in the same manner as noble metal nanocrystals affect it. [68] Thus, the controlled shape and size are also critical factors in the development of active metal/semiconductor nanocomposite for improved H 2 evolution activity.…”

The surface plasmon resonance (SPR) of noble metals is known to improve the efficiency of various processes and devices. The photocatalytic process is the production of fuels and storage of solar photons in chemical bonds without imposing harmful threats to the environment. Photovoltaics are other devices utilizing solar energy for electrical energy. Similarly, other optoelectronic devices like photodetectors absorb photons and convert it into charges via electron–hole dissociation processes. In contrast, light‐emitting optoelectronic devices work based on the phenomenon of charge recombination to produce light. All these devices, however, have efficiency limitations, which impede the application of novel functional materials in these devices. A more direct approach is the utilization of noble metals and their complexes, which significantly enhance the efficiencies of these devices by SPR. This article highlights recent works and applications of noble metals by SPR‐enhanced photocatalysis for hydrogen evolution from water, CO2 conversion into useful compounds, and oxidation of hazardous pollutants. In addition, the plasmon‐enhancement of optoelectronic devices is summarized. Several possible mechanisms that have been previously reported in the literature are discussed in this work, with particular emphasis on different features of these mechanisms involving devices that are not highlighted and therefore need more attention.
