Passivation of interfacial defects serves as an effective means to realize highly efficient and stable perovskite solar cells (PSCs). However, most molecular modulators currently used mitigate such form poorly conductive aggregates at the interface with charge collection layer, impeding extraction photogenerated carriers. Here, a judiciously engineered passivator, 4-tert-butyl-benzylammonium iodide (tBBAI), is introduced, whose bulky tert-butyl groups prevent unwanted aggregation by steric...
Long-term durability is critically important for the commercialization of perovskite solar cells (PSCs). The ionic character and hydrophilicity commonly used additives hole-transporting layer (HTL), such as lithium bis(trifluoromethanesulfonyl)imide (Li-TFSI) tert-butylpyridine (tBP), render PSCs prone to moisture attack, compromising their long-term stability. Here we introduce a trifluoromethylation strategy overcome this drawback boost PSC's electric power conversion efficiency (PCE). We...
The mechanism and origins of Z-selectivity in olefin metathesis with chelated Ru catalysts were explored using density functional theory. approaches from the "side" position catalysts, contrast to reactions previous unchelated that favor bottom-bound pathway. Steric repulsions between substituents on N-substituent N-heterocyclic carbene ligand lead highly selective formation Z product.
Developing hole-transporting materials (HTMs) with appropriate molecular configuration and charge mobility is important to improve perovskite solar cell (PSC) photovoltaic performance their feasibility for commercialization.

Carbon–carbon double bonds are introduced between the core p-methoxyl planarity HTM, favoring intermolecular stacking thus...
Quantum dot light-emitting diodes (QLEDs) based on high-color-purity blue quantum dots (QDs) are crucial for the development of next-generation displays. I-III-VI type QDs have been recognized as eco-friendly luminescent materials QLED applications due to their tunable band gap and high-stable properties. However, efficient blue-emitting remain rare owing high densities intrinsic defects surface defects. Herein, narrow-band blue-emissive CuAlSe2/Ga2S3/ZnS is synthesized via a facile...
Ambimodal reactions involve a single transition state leading to multiple products. In such reactions, theory gives no information about the ratio of products that are formed, and molecular dynamics must be performed predict this ratio. Understanding relationship between structure product is long-standing problem in dynamics. We have studied 15 ambimodal pericyclic investigated TS bond lengths saddle points ratios from trajectory simulations. A linear correlation, ln(B:A) = −9.4(Bond 3 –...
The Z-selective ethenolysis activity of chelated ruthenium metathesis catalysts was investigated with experiment and theory. A five-membered catalyst that successfully employed in cross reactions has now been found to be highly active for at low ethylene pressures, while tolerating a wide variety functional groups. This phenomenon also affects its prohibits crossover internal olefins via trisubstituted ruthenacyclobutane intermediates. In contrast, related containing six-membered...
