Summary: The biosensor fabricated based on CHA, CCP, and GO shows improved sensitivity compared with conventional CHA-based biosensors, providing potential applications for DNA and protein detection through dual signal amplification. The biosensor could also be potentially applied for protein detection by integrating aptamers, as demonstrated with thrombin detection and satisfactory recovery in spiked human serum.

Summary: In this study, a series of novel polymers were synthesized via geminal cross-coupling, incorporating tetraarylethylene segments into the conjugated backbones. These polymers exhibited pronounced aggregation-induced ratiometric fluorescence and aggregations-caused quenching, with a significant dual emission wavelength difference caused by environmental changes, making them suitable for ratiometric fluorescence sensing.

Summary: Fluorescence imaging using PPE-based CPEs has shown remarkable photophysical properties. The overall charge density of CPEs in water affects their photophysical and aggregation features, with less cationic charge leading to lower cytotoxicity. CLSM studies demonstrated efficient penetration of CPEs into MCF-7 cells after 10 hours of incubation.

Summary: A series of biobased conjugated dienes with exo-methylene and a 6-membered ring were prepared from naturally abundant terpenoids bearing an a,beta-unsaturated carbonyl group, and cationically polymerized to form novel biobased cycloolefin polymers with characteristics originating from natural products. These polymers exhibited high reactivity and thermal stability. By copolymerizing dienes with vinyl ethers of varying reactivities, polymers with different structural properties were obtained.

Summary: The scope of Rh-catalyzed C-C bond cleavage/annulation of biphenylene with various aromatic nitriles was investigated. Further Rh- and Ir-catalyzed C-H bond activation/annulation sequence of the resulting 9-arylphenanthridines with alkynes led to the formation of cationic [4], [5], [6] helical quinolizinium salts. The helical arrangement of these compounds was confirmed by single-crystal X-ray analysis. Most of the prepared quinolizinium salts exhibited fluorescence emission with a maximum wavelength in the range of 525-623 nm and absolute quantum yields up to 25%.

Summary: In this article, a novel catalytic reaction using Pd(0) and Bronsted acid is reported for the synthesis of biologically important imidazolidinone-fused N-heterocycles through redox-neutral intramolecular N-allylation of indoles and pyrroles with alkynes. This atom-economical method is applicable to a wide range of substrates and eliminates the need for leaving groups or oxidizing agents commonly used in traditional allylation reactions.

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.
