In 2022,Sun, Yiping; Qu, Hongmei; Zhang, Jiacai; Duan, Xingyu; Zhang, Xiaokun published an article in Tetrahedron. The title of the article was 《Room temperature phosphorescence, thermally activated delayed fluorescence and multicolor mechanochromic luminescence of emitters through molecular interaction and conformational modulations》.Name: 2,4-Dichloropyrimidine The author mentioned the following in the article:
Two novel heavy atom-free pure organic pyrimidine-based asym. donor-acceptor type emitters were designed and synthesized. The twisted D-A conformation was favored to produce small ΔEst and effective ISC. Excitingly, PMBT and CzPMBT showed precious fluorescence-RTP-TADF triple emission. Furthermore, PMBT responded to external stimuli of volatile solvents fumigation and different intensity grinding to generate a multicolor switching system, which included charming white light due to the dual emission of fluorescence and phosphorescence. Crystallog. anal. was conducted to explain the reasons for the differences in photophys. properties produced by the two compounds This research provides insight into the mechanism of action of RTP, TADF and multicolor MCL through intermol. interactions and conformational modulation. The experimental process involved the reaction of 2,4-Dichloropyrimidine(cas: 3934-20-1Name: 2,4-Dichloropyrimidine)
2,4-Dichloropyrimidine(cas: 3934-20-1) is a member of organic chlorides. Organic chloride content in crude oil can be detected through specialized laboratory analysis. Care and attention are essential while sampling and testing.Name: 2,4-Dichloropyrimidine
