Summary: Three novel donor-acceptor-acceptor small molecules with benzotriazole as the central building block are synthesized and investigated for their molecular structure, electrochemical behavior, and optical properties. Vacuum-deposited small-molecule organic solar cells (SMOSCs) fabricated with these molecules and C-70 as the acceptor exhibit power conversion efficiencies (PCEs) in the range of 6.42-7.43%. One of the molecules shows a promising PCE of 14.84% under indoor illumination, demonstrating its potential in indoor photovoltaic applications.

Summary: Small molecule donor/polymer acceptor (SD/PA)-type organic solar cells (OSCs) have attracted attention for their high efficiency and thermal stability. However, their development lags behind polymer donor/small molecule acceptor (PD/SA)-type OSCs. This review analyzes the key factors affecting the photovoltaic performances of SD/PA-type OSCs and provides insights on their future development.

Summary: The impact of internal donor/acceptor groups and pi-spacers in dyesensitized solar cells was investigated in this study. It was found that adding an internal donor/acceptor and using different p-bridges in the D-pi-A arrangement can influence absorption energies and enhance photovoltaic characteristics. The aim of the research is to establish a theoretical foundation for appropriate structural changes and design in the development of efficient DSSCs.

Summary: Manipulating the backbone of SMAs is crucial for developing efficient OSCs. We report a 4-arm acceptor, 4A-DFIC, unexpectedly generated in a reaction. 4A-DFIC exhibits rigid and twisted molecular plane and effective molecular stacking. It shows a low band gap and excellent light-harvesting capability. OSCs based on 4A-DFIC achieved the highest power conversion efficiencies to date for multi-arm SMA-based OSCs.

Summary: The study introduces a polymerized small-molecule acceptor (PJ1) as an interface modulator to optimize the morphology of all-small-molecule organic solar cells (ASM-OSCs) and improve power conversion efficiency. Adding a small amount of PJ1 effectively condenses the morphology, enhances crystallinity, and decreases domain sizes in ASM-OSCs, ultimately leading to accelerated hole transfer and enhanced charge transport.

Summary: This study investigates the aggregation behavior of CO-bridge isomeric small-molecule acceptors in solutions and discovers the impact of large side-chain steric hindrance on molecular self-aggregation. Additionally, the synergistic effect of CO-bridge isomerization, side-chain branching, and end-group fluorination is found to control the pi-pi interactions, leading to the reversal of the aggregation ability of the isomeric small-molecule acceptors.

Summary: A universal strategy for enhancing the photocatalytic activity of polymer photocatalysts under visible light is reported. By introducing a thiophene unit as a pi-spacer between the electron donors and acceptors to form a D-pi-A molecular structure, the conjugation degree and light absorption range of the polymer can be enhanced. The chemical structure of the resulting polymers can also be controlled by adjusting the feed ratio between the electron donors and acceptors. The optimized D-pi-A copolymer photocatalyst shows impressive hydrogen evolution rate under visible light irradiation and can be further improved with the addition of Pt co-catalyst. This strategy can also be applied to other polymeric photocatalysts, demonstrating its universality in enhancing the photocatalytic activity.

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.
