Cao, Chaotun published the artcileQuantifying and fine adjusting the solid-state fluorescence wavelength of 1-thienyl-2-arylethylene, Recommanded Product: 1-(Chloromethyl)-4-(trifluoromethyl)benzene, the publication is Journal of Luminescence (2021), 117895, database is CAplus.

Thirty two 1-thienyl-2-arylethylene derivatives (XAEY) were synthesized and their solid-state fluorescence emission wavelengths Em (nm) were determined The effects of substituents X and Y on the fluorescence wavelengths were analyzed in detail. The quant. correlation anal. for the Em was carried out by employing the ground-state polarity parameters and excited-state parameters of the substituents X and Y. A quant. equation was obtained and its reliability was verified by the leave-one-out (LOO) method. The obtained results show: (1) For the compounds XAEY, when the group Y on the aryl group is fixed, the Em order is 2′-methyl-2-thienyl-AEY > 3-thienyl-AEY > 2-thienyl-AEY; when thienyl (X) is fixed, the Em of XAEY with electron-withdrawing group Y is longer than that of XAEY with electron-donating group Y; (2) The Em of XAEY can be finely adjusted by changing groups X and Y. That is, one can obtain a series of compounds with continuous fluorescence emission wavelength in range of 450-600 nm via selecting different groups X or Y. (3) The 2′-Me has an addnl. red shift effect on the Em of 2′- methyl-2-thienyl-AEY. The results of this paper can provide an important reference for studying theor. solid-state fluorescence emission spectra of organic compounds and designing corresponding fluorescent material mols.

Jin, Piaopiao published the artcileMulti-responsive diarylethene-phenolphthalein hybrids by multiple stimuli, COA of Formula: C15H14Cl2S2, the publication is Tetrahedron (2016), 72(35), 5488-5494, database is CAplus.

Photochromic diarylethene derivatives cherishing phenolphthalein moieties were designed and constructed. We present efforts to investigate their versatile performances in multi-responsive properties with multiple stimuli of light, acid/base and temperature/heat. Results show their fluorescence could be on-off switched not only by different lights but also by acid/base. Besides lights and acid/base controllable color change and fluorescence-changing, altering phase states could also tune their colors via different temperature, which is rare performance for diarylethene derivatives Especially, the photocyclization ratio is as high as 100% for compound 2o bearing two phenolphthalein groups. These versatile properties are helpful to the design of pH sensitive photoswitches, fluorescent sensors, and mol. logical gates.

Xu, Jinhui published the artcileUnveiling Extreme Photoreduction Potentials of Donor-Acceptor Cyanoarenes to Access Aryl Radicals from Aryl Chlorides, Related Products of chlorides-buliding-blocks, the publication is Journal of the American Chemical Society (2021), 143(33), 13266-13273, database is CAplus and MEDLINE.

Since the seminal work of Zhang in 2016, donor-acceptor cyanoarene-based fluorophores, such as 1,2,3,5-tetrakis(carbazol-9-yl)-4,6-dicyanobenzene (4CzIPN), have been widely applied in photoredox catalysis and used as excellent metal-free alternatives to noble metal Ir- and Ru-based photocatalysts. However, all the reported photoredox reactions involving this chromophore family are based on harnessing the energy from a single visible light photon, with a limited range of redox potentials from -1.92 to +1.79 V vs SCE. Here, we document the unprecedented discovery that this family of fluorophores can undergo consecutive photoinduced electron transfer (ConPET) to achieve very high reduction potentials. One of the newly synthesized catalysts, 2,4,5-tri(9H-carbazol-9-yl)-6-(ethyl(phenyl)amino)isophthalonitrile (3CzEPAIPN), possesses a long-lived (12.95 ns) excited radical anion form, 3CzEPAIPN^•-*, which can be used to activate reductively recalcitrant aryl chlorides (E_red ≈ -1.9 to -2.9 V vs SCE) under mild conditions. The resultant aryl radicals can be engaged in synthetically valuable aromatic C-B, C-P, and C-C bond formation to furnish arylboronates, arylphosphonium salts, arylphosphonates, and spirocyclic cyclohexadienes.
