Summary: DTPs represent a class of antiaromatic compounds with high thermal stability and red-shifted electronic absorption, attributed to narrower HOMO-LUMO gap compared to their analogs. They prefer offset face-to-face packing motifs in solid-state structure, and thienyl-substituted DTPs with hydrophilic side chains exhibit thermochromic behavior in polar solvents due to aggregate formation.

Summary: Organic fluorophores are crucial for organic optoelectronic and bioelectronic applications. The enhancement of fluorescence in bromo-organic aggregates, which breaks the traditional belief of heavy-atom effect leading to fluorescence quenching, is achieved by the limited acceleration of intersystem crossing process and the large reduction of vibronic coupling of singlet excitons caused by bromine atoms. The excited-state dynamics further demonstrate that bromine substituents decelerate the internal conversion process and result in slow ISC rates, leading to abnormal fluorescence enhancement.

Summary: The development of solid-state near-infrared (NIR)-emissive pi-conjugated polymers (CPs) has been difficult due to the lack of guidelines for avoiding aggregation-caused quenching. In this study, we designed new electron acceptors with vertically projected bulky substituents at boron to prevent intermolecular interactions and achieved near-infrared emission in solid-state. The introduction of vertically projected bulky substituents at boron opens up a new research field for solid-state NIR-emissive materials.

Summary: A new series of ferrocene and methoxyphenyl conjugated push-pull chromophores were synthesized and characterized. The structure of one of the chromophores was confirmed by X-ray diffraction analysis. Non-covalent interactions were observed in the crystal packing. The thermal stability and solvatochromic properties of the chromophores were investigated. The chromophores showed low fluorescence intensity but were enhanced by aggregation-induced emission. The second-order nonlinear optical response of one of the chromophores was comparable to a standard material. Density functional theory was used to analyze the optical and nonlinear optical properties.

Summary: Conjugated polymers consisting of boron formazanate in the main chains were prepared with donor-type comonomers and evaluated for their electronic structures. The polymers exhibited deep-red and NIR absorption and emission bands, with remarkable NIR emission from a polymer composed of formazanate and fluorene. The boron formazanate acts as a strong electron-accepting unit in main-chain conjugation, resulting in intramolecular charge transfer emission. Additionally, wavelength-conversion materials from visible to NIR light were successfully demonstrated by modifying polymer structures.

Summary: A new molecular design involving hypervalent compounds with germanium-fused azobenzene scaffolds has been discovered to exhibit near-infrared (NIR) emission. The unique optical properties are attributed to the trigonal bipyramidal geometry of the hypervalent compounds formed by combination of germanium and azobenzene-based ligands. The hypervalent bond formation significantly narrows the HOMO-LUMO energy gap, and extension of pi-conjugation further enhances the narrow-energy-gap property.

Summary: This study presents the design and synthesis of sulfated disaccharide inhibitors based on IdoA(2S)-GlcNS(6S), which showed potent inhibition of Sulf-2. The results suggest that IdoA(2S)-GlcNS(6S) is the shortest fragment size required for effective inhibition of Sulfs, and a trisulfated disaccharide is identified as the minimal fragment size of heparan sulfate for effective endosulfatase inhibition.

Summary: The self-adaptability of galvanostatic electrolysis was found to be helpful in a multistage chemo- and diastereoselective electrochemically promoted cyclodimerization of chalcones. Through a series of reductive events, densely functionalized cyclopentanes with five contiguous stereocenters were obtained (25 examples, yields up to 95%, dr values up to >20:1). Further experimental and electrochemical investigations indicated the crucial role of dynamic kinetic resolution of the aldol intermediate in the reaction mechanism.

Summary: In this study, the synthesis of functionalized benzo[a]phenazines and indazolo[2,3-a]quinolines was achieved through Rh(III)-catalyzed oxidative annulation of 2-arylquinoxalines and 2-aryl-2H-indazoles with allyl alcohols. The method showed a wide substrate scope, excellent functional group tolerance, good to high yields of annulated products, and the capability for scaled-up synthesis. A tentative mechanism of the annulation reaction was proposed based on a preliminary mechanistic investigation.
