Summary: Herein we demonstrate that combining buckybowl corannulene with thiophene-S,S-dioxide motifs is an effective method for synthesizing molecular materials with high electron affinity. The synthesis process is modular and involves thienannulation of corannulene-based phenylacetylene scaffolds. The resulting compounds are highly soluble in organic solvents and exhibit interesting optical properties in the blue/green regions of the electromagnetic spectrum. Importantly, a bis-S,S-dioxide derivative shows three reversible reductions similar to the widely used fullerene-based electron acceptor PC61BM.

Summary: This study investigates the interaction between three different nonfullerene acceptors (NFAs) with varied chemical structures in bulk-heterojunction (BHJ) blends. It is found that the compatibility between the NFAs and the polymer donor increases as the position of the monochlorinated end groups changes, resulting in different BHJ morphologies. Among these morphologies, the MQ1-8 blend exhibits the highest photoconversion efficiency.

Summary: In this study, we investigated the structural and optical properties of imide-fused polycyclic aromatic hydrocarbons (IPAHs) and their radicals using the variational Davydov ansatz parametrized by density functional theory. Our calculations revealed that hydrogen plays a crucial role in the formation of radicals and the generation of a mid-gap polaronic state. The simulations of UV-vis absorption spectra and NIR absorption signals supported our findings and demonstrated the formation of radical-radical bonding (pancake bonding) as the physical basis for long-range ferromagnetic orders. Additionally, we predicted the absorption spectra of perylene diimide (PDI), terrylene diimide (TDI) and their radicals.

Summary: Regioregular polythiophenes have been widely used in organic electronic applications due to their solution processability with chemical modification through side chain engineering, as well as their microstructural organization and good hole transport properties. The introduction of alkylthio side chains showed improved crystallinity and charge mobility in polythiophene semiconductors, with branched side chains helping to solve the issue of low regioregularity and enhancing the overall performance of OFET devices.

Summary: Two novel nonfused-ring electron acceptors (N-FREAs), DTP-out-F and DTP-in-F, containing a 2,5-difluorophenylene core with DTP blocks and IC-2F terminals, were designed and synthesized. The isomerization of DTP to 2,5-difluorophenylene affected the overall properties of the N-FREAs, leading to improved power conversion efficiency. The isomerization strategy shows great potential in developing high-performance N-FREAs.

Summary: Pure organic mechanoluminescent materials are environmentally friendly and can be mechanically stimulated by external force. By strengthening intermolecular C-Hπ interactions in the ML-inactive thioxanthene derivatives TxPh, a new compound TxPhTh with bright mechanoluminescence was obtained. The enhanced C-Hπ interactions suppressed non-radiative transition channels and increased the photoluminescence quantum yield of crystalline TxPhTh. This research provides a new approach for designing mechanoluminescent materials and advances the understanding of their mechanism.

Summary: In this article, the correlation between the structural properties of three polycyclic arene-fused selenophenes with different crystal packing and their mobility was investigated. The energy gap between HOMO and LUMO was found to be a determining factor for their hole mobilities. The theoretically calculated anisotropic mobility was also correlated to evaluate their performance as a donor in solar cell devices. It was found that Nap-Se2 exhibited the highest mobility among the three selenophenes.

Summary: A twisted node modulation strategy is proposed to address the challenges of controlled interlayer stacking, solvent processing, and long-afterglow luminescence in two-dimensional covalent organic frameworks (2D-COFs). By introducing twisted and non-twisted nodes alternately, a reversible crystal transformation is achieved between eclipsed and inclined stacking. The inclined COFs can be easily exfoliated into nanosheets for solution processing. Programmatic long-afterglow luminescence is achieved by confining isolated exfoliated nanosheets within polymethyl methacrylate for various functional applications.

Summary: This study investigates the O-2 adsorption and reduction on cobalt porphyrin (CoOEP) and phthalocyanine (CoPc) using in situ electrochemical scanning tunneling microscopy (ECSTM). Results show higher ORR activity of CoOEP compared to CoPc. Molecular-level imaging reveals that O-2 adsorbs mainly on Co-II sites and exhibits higher contrast in ECSTM images on CoOEP compared to CoPc. The dynamics of O-2 adsorption are quantitatively measured, with CoOEP exhibiting higher binding dynamics and lower Co-O dissociation barriers compared to CoPc.

Summary: The in situ electrochemical scanning tunneling microscopy (ECSTM) study of O2 adsorption and reduction on cobalt porphyrin (CoOEP) and phthalocyanine (CoPc) is reported. CoOEP exhibits higher ORR activity than CoPc according to electrochemical measurements. Self-assembled CoOEP and CoPc monolayers on Au(111) substrates are observed at molecular resolution by ECSTM. O2 adsorbs on CoII sites and has high contrast in ECSTM images for both CoOEP-O2 and CoPc-O2 complexes. The surface coverage of CoOEP-O2 is approximately 1.4 times higher than that of CoPc-O2. The dynamics of O2 adsorption, quantitatively measured by potential step experiments, indicate higher dynamics and lower barriers for Co-O dissociation on CoOEP compared to CoPc.

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.

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.
