Summary: In this study, we synthesized and characterized luminescent liquid crystals based on 2,1,3-benzoxadiazole (BOX) with a pi-conjugated core and elongated donor units connected by triple bonds. These molecules exhibited thermotropic mesomorphism with nematic and smectic phases and showed intense photoluminescence under UV-vis light excitation. The quantum yields and excited state lifetimes were influenced by the nature of the donor unit, and solvatochromism studies revealed a dependence on solvent polarity.

Summary: Designing N-coordinated porous single-atom catalysts (SACs) is a promising approach for enhanced energy conversion. This study reports two efficient SAC systems, Co@rhm-PorBTD and Co@sql-PorBTD, based on Co(II)-porphyrin/ [2,1,3]-benzothiadiazole (BTD) covalent organic frameworks (COFs), for O2 electrocatalysis. Experimental results show that these COFs outperform commercial Pt/C by a large margin. The design and electrochemical performance of these COFs offer a pyrolysis-free bottom-up approach that avoids creating random atomic sites or unpredictable structural features.

Summary: Intense red-emitting heteroleptic Cu(I) complexes were isolated, and their structures were determined using X-ray diffraction. The complexes showed strong luminescence with photoluminescence quantum yields up to 46% when excited with UV and violet-blue light. DFT calculations revealed that the lowest energy absorptions involved charge transfer from the CuP2 fragments to the unoccupied pi* orbital of BTD, and the triplet -> singlet emissions involved the metal center, phosphine ligands, and occupied and empty orbitals of BTD.

Summary: This study aimed to evaluate the effects of vitamin D3 on spatial memory and cytokine levels in geriatric rats. The results showed that vitamin D3 supplementation improved spatial memory in rats aged 6, 13, and 22 months, and it also improved spatial memory in 31-month-old rats at a high dose. The lower dose mainly regulated inflammatory cytokines in the frontal cortex. These findings suggest that vitamin D3 may have an immunomodulatory effect on aging.

Summary: This study presents the synthesis and characterization of ZnO nanoparticles using starch-assisted sol-gel route with corn and potato starches. The botanical source of starch was found to influence the crystallite size and optical properties of the ZnO nanoparticles. The resulting ZnO nanopowders were obtained with sizes of 26 nm and 23 nm (Scherrer method) using corn and potato starches, and 22 nm and 14 nm (Williamson-Hall method) using the same starches, respectively. The band gap energies were estimated to be around 3.05 to 3.08 eV (Tauc method) and 3.36 to 3.38 eV (effective mass model). The results indicate that the type of botanical source used for starch plays a role in the crystallite size and optical properties of ZnO nanopowders obtained through this sol-gel route.

Summary: In this report, we synthesized substituted indolizines using ultrasound irradiation in a one-pot and multicomponent strategy, and studied their photophysical properties. The compounds exhibited absorption maxima in the UV-A-violet region and their electronic transitions were related to allowed 1 pi ->pi* transitions. Indolizines showed fluorescence in the violet-to-green region, and the ground and excited states were influenced by the substituents in the indolizine core. The role of solvent in the deactivation of excited states was critical for exploring these compounds as optical sensors for benzene.
