In 2018,Chen, Zhao; Liu, Gang; Pu, Shouzhi; Liu, Sheng Hua published 《Triphenylamine, carbazole or tetraphenylethylene-based gold(I) complexes: Tunable solid-state room-temperature phosphorescence and various mechanochromic luminescence characteristics》.Dyes and Pigments published the findings.Application In Synthesis of 3,5-Dibromoaniline The information in the text is summarized as follows:
Three novel gold(I) complexes based on triphenylamine, carbazole or tetraphenylethylene moiety were successfully designed and synthesized. Meanwhile, their structures were characterized by NMR spectroscopy and elemental anal. Their solid-state luminescence characteristics were surveyed by photoluminescence spectroscopy, and their distinct mech. stimulus-responsive behaviors in the solid state were also studied by photoluminescence spectroscopy. The solid-state phosphorescence and emission lifetimes of these mononuclear gold(I) complexes 1-3 could be tuned by introducing different fluorophores involving triphenylamine, carbazole or tetraphenylethylene. Also, luminogen 1 exhibited switchable mechanochromic luminescence behavior with color change from yellow to colorless, and the solid-state luminescence on-off mechanochromism between yellow-green and colorless of luminogen 2 could also be observed However, no mechanochromism phenomenon was observed for tetraphenylethene-containing luminogen 3. The powder x-ray diffraction results suggested that the unusual high-contrast mechanochromism characteristics of luminogens 1 and 2 could be attributed to a crystalline-to- amorphous morphol. transition. After reading the article, we found that the author used 3,5-Dibromoaniline(cas: 626-40-4Application In Synthesis of 3,5-Dibromoaniline)
3,5-Dibromoaniline(cas: 626-40-4) belongs to anime. Large quantities of aliphatic amines are made synthetically. The most widely used industrial method is the reaction of alcohols with ammonia at a high temperature, catalyzed by metals or metal oxide catalysts (e.g., nickel or copper). Mixtures of primary, secondary, and tertiary amines are thereby produced.Application In Synthesis of 3,5-Dibromoaniline
