Discovery of full color emissive thiazole fluorophores in solution and solid states: The core is central and regulating torsional barrier does the trick!

Sulfone/Carbonyl‐Based Donor‐Acceptor Fluorescent Dyes: Synthesis, Structures, Photophysical Properties and Cell Imaging

“…Materials and characterization methods: 9,9-Dihexylfluorene-2,7diboronic acid bis(pinacol) ester, 2-bromophenyl methyl sulfoxide, phosphorus pentoxide, triflic acid, 3-chloroperbenzoic acid, Nbromosuccinimide, N,N-diphenyl-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)aniline, Pd(PPh 3 ) 4 , methyl 5-bromo-2-iodobenzoate and (4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2H-tetrazolium bromide (MTT) were purchased from Energy-Chemical Co., Ltd. 1 H and 13 C NMR spectra were measured on a JEOL 400YH spectrometer with tetramethylsilane as the internal standard. Infrared spectra were recorded on a Nicolet iS20 FTIR spectrometer (Thermo Scientific) equipped with a diamond ATR unit and are reported in terms of frequency of absorption [cm À 1 ].…”

Electrochemical single-step N-acylation and S-cyclization synthesis of thiazolimide via radical process

“…Thiazole is also ubiquitous in fluorescent dyes, since the unique framework could be employed as a π-electron bridge. [30][31][32][33] The high medicinal significance and luminous characteristics of this scaffold have drawn the attention of researchers resulting in the dissemination of several reports discussing the synthesis of various thiazole derivatives. [34][35][36] Specifically, thiazolimide containing polar side chains have been shown to effectively improve the thermoelectric properties of organic materials.…”

Fusing rigid planar units to engineer twisting molecules as dual-state emitters

“…17 Nonetheless, the molecular design principle of DSEgens remains unclear at the current stage and the fundamental understanding of the luminescent mechanism still needs further investigation. 18 Some luminescent cores, such as a College of Chemistry and Chemical Engineering, Key Laboratory of Structure and Functional Regulation of Hybrid Materials (Anhui University), Ministry of Education, Photoelectric Conversion Energy Materials and Devices Key Laboratory of Anhui Province, Anhui University, Hefei, 230061, P. R. China. E-mail: jxyang@ahu.edu.cn b College of Chemistry and Chemical Engineering, Xinyang Normal University, Xinyang, 464000, P. R. China.…”

“…Nonetheless, the molecular design principle of DSEgens remains unclear at the current stage and the fundamental understanding of the luminescent mechanism still needs further investigation. 18 Some luminescent cores, such as tetraphenylethene (TPE), 19,20 triphenylamine, 21,22 cyanostilbene, 23 coumarin, 24 perylene diimides (PDIs), 25 carbazole, 26 and a few others, 27–29 so far have been reported to serve as scaffolds for engineering DSEgens. Navigation into the molecular structures reveals the critical importance of the delicate balance between the twisting conformation and rigid conjugation to achieve the DSE.…”
