Zhang, Huimiao;Toy, Patrick H. research published 《 Halogen Bond-Catalyzed Friedel-Crafts Reactions of Furans Using a 2,2′-Bipyridine-Based Catalyst》, the research content is summarized as follows. A halogen bond donor based on a 2,2′-bipyridine framework I has been synthesized, and used to catalyze Friedel Crafts reactions of furans II (R = H, Me, t-Bu). Electrophiles used successfully in these reactions included various enones such as 3-buten-2-one, crotonophenone, cyclohexenone, etc.; benzaldehyde, and acetic anhydride. The yields of the reactions were generally good using a moderate catalyst loading (0.025 or 0.1 equivalent) at a relatively low temperature (room temperature or 50°C) in acetonitrile. The catalyst was designed with a biaryl scaffold so that if it indeed proved to be an efficient halogen bond donor organocatalyst, an enantioenriched version of it could potentially serve as a stereoselective catalyst.

Xu, Xiaojia;Ji, Xiaoyu;Chen, Rui;Ye, Fangyuan;Liu, Shuaijun;Zhang, Shuo;Chen, Wei;Wu, Yongzhen;Zhu, Wei-Hong research published 《 Improving Contact and Passivation of Buried Interface for High-Efficiency and Large-Area Inverted Perovskite Solar Cells》, the research content is summarized as follows. Inverted-structured perovskite solar cells (PSCs) mostly employ poly-triarylamines (PTAAs) as hole-transporting materials (HTMs), which generally result in low-quality buried interface due to their hydrophobic nature, shallow HOMO levels, and absence of passivation groups. Herein, the authors molecularly engineer the structure of PTAA via removing alkyl groups and incorporating a multifunctional pyridine unit, which not only regulates energy levels and surface wettability, but also passivates interfacial trap-states, thus addressing above-mentioned issues simultaneously. By altering the linking-site on pyridine unit from ortho- (o-PY) to meta- (m-PY) and para-position (p-PY), they observed a gradually improved hydrophilicity and passivation efficacy, mainly owing to increased exposure of the pyridine-nitrogen as well as its lone electron pair, which enhances the contact and interactions with perovskite. The open-circuit voltage and power conversion efficiency (PCE) of inverted-structured PSCs based on these HTMs increased with the same trend. Consequently, the optimal p-PY as HTM enables facile deposition of uniform perovskite films without complicated interlayer optimizations, delivering a remarkably high PCE exceeding 22% (0.09 cm²). Moreover, when enlarging device area tenfold, a comparable PCE of over 20% (1 cm²) can be obtained. These results are among the highest efficiencies for inverted PSCs, demonstrating the high potential of p-PY for future applications.

Aromatic triangular tri-palladium cations, abbreviated as [Pd₃]⁺, have shown interesting photoelec. properties, Lewis basic character, and excellent activities in catalytic hydrogenation. Herein, authors report the highly efficient and C-I selective Sonogashira and Heck coupling reactions catalyzed by these tri-palladium complexes. Benefiting from the moderate C-I bond association energy, these tri-palladiums presented exclusive reactivities to aryl iodides over the brominated aromatics in coupling reactions. In the Sonogashira pathway, good to excellent isolated yields (71-95%) were achieved. Gram-scale reaction reached 93% of yield with palladium loading as few as 0.06 mol %. Authors also explored the electronic and steric effects for Ph alkynes and aryl iodides including heteroaromatics like thiophene, pyridine, pyrazole, and pyrazine. Similarly, yields of 71-96% were obtained for palladium loading of 1.5 mol% through catalyzed Heck coupling of aryl iodides and alkenes. The HRMS monitoring revealed that [Pd₃]⁺ maintained as whole entity during the catalytic process due to its robusness.
