Gong, Jun;Huang, Ruishan;Wang, Chunfei;Zhao, Zujin;Tang, Ben Zhong;Zhang, Xuanjun research published 《 Circularly polarized luminescent 4,4′-bicarbazole scaffold for facile construction of chiroptical probes》, the research content is summarized as follows. Small mols. with circularly polarized luminescence (CPL) are especially valuable in solution-based applications, like chiroptical probes for effective sensing. Such application was not well explored due in part to hard introduction of appropriate triggerable fluorophores. An easily post-modifiable CPL-active scaffold (4) is reported, and a feasible strategy to construct chiroptical probes for sensing hypochlorous acid is further proposed. Helically chiral 4 with a 4,4′-bicarbazole scaffold exhibits a large Stokes shift ≤142 nm and g_lum value of 0.9 × 10^-3. Through facile construction of phenothiazine moiety on 4, red-emitting compound 5 was obtained in high yield (85.3%), showing distinct optical and chiroptical responses towards hypochlorous acid with good liner relations and CPL sign blue-shifting of 120 nm in vitro. The probe is also applied to detect endogenous hypochlorous acid in living macrophages and can serve as a CPL sensor. Taking 5 as an application example, the authors envision that CPL-enabling scaffold 4 could find broad use in the design of more chiroptical probes.

B.;Pereira, Mariette M. research published 《 Al(III) phthalocyanine catalysts for CO₂ addition to epoxides: Fine-tunable selectivity for cyclic carbonates versus polycarbonates》, the research content is summarized as follows. A sustainable synthetic methodol. to prepare bifunctional cationic imidazolyl and neutral tert-butylphenoxy Al(III)-phthalocyanine complexes is described, using ultrasound irradiation to synthesize the phthalonitrile precursors, followed by microwave-assisted cyclotetramerization. The metallophthalocyanine catalysts were applied in the coupling reaction of CO₂ with epoxides, where the structure of the phthalocyanine was shown to determine the reaction selectivity towards the formation of cyclic carbonates vs. polycarbonates. The cationic imidazolyl phthalocyanines operate as efficient bifunctional catalysts to promote the CO₂ cycloaddition to terminal epoxides (styrene oxide, epichlorohydrin, propylene oxide and allyl glycidyl ether), leading to TONs up to 1414 and 100% selectivity for cyclic carbonates, without the need of using any co-catalyst. On the other hand, the neutral 4-tert-butylphenoxy Al(III) phthalocyanine catalyzed the copolymerization reaction between CO₂ and cyclohexene oxide, in the presence of PPNCl as co-catalyst, with TON = 814, providing the first example of a metallophthalocyanine catalyst with full selectivity for formation of polycarbonates.

Gonzalez-Rodriguez, Edgar;Guzman-Juarez, Brenda;Miranda-Olvera, Montserrat;Carreon-Castro, Maria del Pilar;Maldonado-Dominguez, Mauricio;Arcos-Ramos, Rafael;Farfan, Norberto;Santillan, Rosa research published 《 Effect of the π-bridge on the light absorption and emission in push-pull coumarins and on their supramolecular organization》, the research content is summarized as follows. A family of eight π-extended push-pull coumarins with cross-conjugated (amide) and directly conjugated (p-phenylene, alkyne, alkene) bridges were synthesized through a convergent strategy. Using an exptl. calibrated computational protocol, their UV-Visible light absorption and emission spectra in solution were investigated. Remarkably, amide-, alkyne- and alkene-bridges undergo comparable vertical excitations. The different nature of these bridges manifests during excited-state relaxation and fluorescence. These mols. can serve as building blocks for p-type semiconductors with low reorganization energies, below 0.2 eV. Since solid-state self-assembly is crucial for this application, the effect of the π-bridge over the supramol. organization in this family of compounds was examined to determine if stacking prevails in these π-extended coumarin derivatives Amide and alkyne spacers allow coplanar conformations which crystallize readily; p-phenylene hinders planarity yet allows facile crystallization; alkene-bridged mols. eluded all crystallization attempts. All the crystals obtained feature dense face-to-face π-stacking with 3.5-3.7 Å interlayer distances, expected to facilitate charge transfer processes in the solid state.

Cu-catalyzed 1,3-dipolar cycloaddition of Et 2-azidoacetate to iodobuta-1,3-diynes and subsequent Sonogashira cross-coupling were used to synthesize a large series of new triazole-based push-pull chromophores: 4,5-bis(arylethynyl)-1H-1,2,3-triazoles I (R¹ = Cl, -CN, -N(Me)₂, NO₂; Ar = 4-MeOC₆H₄, 4-NC-C₆H₄, 2-(Me)₂N-C₆H₄, etc.). The study of their optical properties revealed that all mols. have fluorescence properties, the Stokes shift values of which exceed 150 nm. The fluorescent properties of triazoles are easily adjustable depending on the nature of the substituents attached to aryl rings of the arylethynyl moieties at the C4 and C5 atoms of the triazole core. The possibility of 4,5-bis(arylethynyl)-1,2,3-triazoles’ application for labeling was demonstrated using proteins and the HEK293 cell line. The results of an MTT test on two distinct cell lines, HEK293 and HeLa, revealed the low cytotoxicity of 4,5-bis(arylethynyl)triazoles, which makes them promising fluorescent tags for labeling and tracking biomols.

Gregory, Carolyn;Silva, Weslley G. D. P.;van Wijngaarden, Jennifer research published 《 Rotational spectrum and quantum chemical calculations of methyl cyanoacetate: A compound of potential astrochemical interest》, the research content is summarized as follows. The rotational spectrum of Me cyanoacetate (H₃CO(CO)CH₂CN) was investigated for the first time using Fourier transform microwave spectroscopy in the 6-19 GHz range. The observed spectral pattern is that of a single, dominant conformer and reveals both ¹⁴N quadrupole hyperfine structure and characteristic A/E splittings due to the Me internal rotor. The rotational constants determined from anal. of the complex spectral pattern confirm that the observed spectrum is that of the lowest energy conformer of Me cyanoacetate predicted at the B3LYP-D3(BJ) and MP2 levels of theory using the aug-cc-pVTZ basis set. This global min. corresponds to a geometry which orients the C-O-C=O and C-C-C=O dihedral angles in syn and near anti arrangements, resp. and is governed by a balance of stabilizing orbital interactions and destabilizing steric effects identified using non-covalent interaction and natural bond orbital analyses.
