Summary: Two novel organic sensitizers, TP1 and TP2, were designed for Dye-Sensitized Solar Cells (DSSC). TP1 followed the classical D-A-p-A design, while TP2 had a symmetric structure with double anchoring functions. Both compounds were synthesized using direct arylation strategies and possibly one-pot desymmetrization. TP1 showed broad and intense light absorption, while TP2 displayed localized absorption in the center of the visible region. Test devices achieved power conversion efficiencies as high as 5.2% under full sun intensity. The transparent DSSC containing TP2 met the transparency requirements for building-integrated photovoltaics (BIPV) and transmitted light that matched the human eye sensitivity spectrum.

Summary: In this study, a series of novel V-shaped derivatives were designed and investigated for their electrochemical, photophysical and nonlinear optical properties. The [1,2,5]oxadiazolo[3,4-b]pyrazine fragment was found to be a strong electron-withdrawing group. All compounds exhibited emissions in the solid state, while only the quinoxaline derivatives emitted in a DCM solution. The quinoxaline derivatives demonstrated solvatochromism and extra-large Stokes shifts, indicating twisted intramolecular charge transfer excited states and aggregation induced emission.

Summary: This review summarizes the applications of side chain-fluorinated amino acids in medicinal chemistry and protein science. The paper outlines strategies for incorporating fluorine atoms into amino acid side chains and elaborating these building blocks into more complex fluorinated peptides and proteins. It then describes the diverse benefits of fluorine in amino acid side chains, including enabling 19F NMR and 18F PET imaging applications, enhancing pharmacokinetic properties, controlling molecular conformation, and optimizing target-binding.

Summary: A highly efficient tandem process for the synthesis of aromatic oxazaheterocycles has been disclosed, involving palladium-catalyzed double-bond isomerization of long-chain olefins and subsequent intramolecular cyclization promoted by B-2(OH)(2). This strategy also enables rapid access to pyrido[3,4-b]indoles, trans-2-olefins, and eneamides with high regio- and stereoselectivity.

Summary: This study explores the use of side-chain engineering for nonfullerene acceptors (NFAs) in indoor organic photovoltaics. By synthesizing two NFAs and modifying their side chains, the absorption is red-shifted and energy levels are aligned. The study achieves an impressive 23.2% power conversion efficiency in fluorinated OPVs under LED lighting, which increases to 28.3% in ternary OPVs with PM6:Y6:halogenated NFA blends, enhancing performance under indoor lighting.

Summary: In this study, a practical method for synthesizing 3-fluorothiophene as pi-bridge units on the polymer backbone was proposed to reduce synthesis steps and lower costs. The introduction of fluorine atoms into the polymer backbone significantly improved the photovoltaic device performance, surpassing traditional methods. In addition, utilizing fluorinated pi-conjugated bridges for photovoltaic device fabrication showed higher efficiency and better performance.

Summary: In this study, two structurally novel diarylethene chemosensors based on a styrene-linked pyrido[2,3-b] pyrazine unit were synthesized via Heck coupling reaction. These chemosensors exhibited quick colorimetric sequential responses towards Hg2+ and then Sn2+, with the formation of a new complex 1O-Hg2 thorn leading to significant quenching of fluorescence intensity. Moreover, 1O-Hg2 thorn could be used as a platform for rapid detection of Sn2+ with noticeable fluorescence enhancement.

Summary: A series of poly-3-alkylthiophenes (P3ATs) with different side-chains were successfully synthesized using Grignard metathesis polymerization, showing well-defined molecular weights and crystalline properties dependent on molecular weights. The UV-Vis spectra of P3ATs in solution exhibited a red shift, indicating an extended effective conjugation in longer chain polymers, and the photovoltaic device performances of P3BT and P3HT samples significantly improved after blending and annealing.

Summary: We designed and synthesized pyrido[3,4-d]pyrimidine derivatives as novel necroptosis inhibitors capable of suppressing the phosphorylation of MLKL. Our SAR studies revealed that compound 20 exhibited comparable inhibitory activity against RIPK3-mediated pMLKL in HT-29 cells relative to the selective inhibitor GSK872. Furthermore, 20 demonstrated selectivity towards RIPK3 over RIPK1 and inhibited necroptosis by impeding MLKL oligomerization.

Summary: In this study, a series of neutral green/gray electrochromic materials were developed by tuning the performance of pyrido[4,3-b]pyrazine-EDOT hybrid polymers. The synthesized precursors/polymers were characterized comprehensively in terms of optoelectronic, morphological, computational, electrochemical, and electrochromic properties. The introduction of a methyl-substituted pyrido[4,3-b]pyrazine acceptor improved the solubility of the precursors and the redox stability of the corresponding polymers, resulting in excellent electrochromic performance in the near-infrared region.

Summary: Nonfullerene acceptor organic solar cells with power conversion efficiency up to 18% show the formation of NFA triplet exciton as a main non-radiative recombination and energy loss channel. Side-chain fluorination in high-efficiency NFA OSCs efficiently inhibits charge recombination to NFA triplet excitons, leading to higher V-OC and PCE. This paves the way for OSCs with lower V-OC loss and efficiency exceeding 20%.
