Transfer of photoexcited charge from PbS nanocrystals to ligand molecules is investigated in different solvents. We find that the transfer rate increases dramatically with solvent dielectric constant. This trend accounted for by a modified Marcus theory incorporates only static effects. The choice allows significant control process. As an important example, we dispersed water exhibit rates 1000 times higher than same organic solvent. Rapid extraction will be efficient nanocrystal-based...

2,5-Diarylarsoles were easily synthesized from nonvolatile arsenic precursors. Diiodoarsine was generated in situ and reacted with titanacyclopentadienes to give 2,5-diarylarsoles. The structures optical properties studied comparison those of 2,5-diarylphosphole. It found that the arsoles much more stable air than phosphole. Single crystal X-ray diffraction revealed atoms adopted a trigonal pyramidal structure, reflecting on s-character lone pair. obtained 2,5-diarylarsoles...

The dithienoarsole skeleton can be safely and easily constructed, by a method superior to conventional synthetic routes. obtained dithienoarsoles, including main-chain type polymer, show luminescence not only in solution but also the solid state.

Dibenzo[b,f]arsepins possessing severely distorted cores compared to those of other heteropins were synthesized. These derivatives exhibited dual photoluminescence in the green-to-red region (500-700 nm) and near-ultraviolet (<380 nm), which could be attributed planarization arsepin core lowest singlet excited (S1 ) state. The computational approach for assessment aromatic indices revealed that dibenzoarsepins studied show aromaticity (8π system) S1 states line with Baird's rule. lone pair...

Pnictogen (Pn = As, Sb, Bi)‐bridged sulfoximines were synthesized by introducing phenyl (Ph) and benzyl (Bn) groups onto the nitrogen atom. Single‐crystal X‐ray diffraction analysis density functional theory (DFT) calculations revealed a weak closed‐shell interaction between Pn N or O. As‐ Sb‐bridged with Bn group exhibited dual fluorescence in solution, while others primarily showed single emission. The viscosity polarity of solvent significantly affected dual‐emission behavior. DFT...

Heteroarene‐fused heteroles have attracted considerable attention owing to their unique electronic and photophysical properties. The bridging element plays a crucial role in determining the characteristics of resulting π‐conjugated molecules. In this study, we synthesized series heteroarene‐fused benzo[b]arsoles investigated structures All arsoles exhibited phosphorescence at 77 K, whereas arsole oxide did not. intensities pnictogen‐containing (phosphorus arsenic) were significantly higher...

Abstract The introduction of chirality into siloxanes is crucial for applications in chiral separation, recognition, and reaction environments. Cage silsesquioxanes, with their distinct three-dimensional structures, offer great potential this field. Here, we utilized corner-opened polyhedral oligomeric silsesquioxane (CO-POSS) to construct unsymmetrical structures cage-centered chirality. three silanol groups commercially available CO-POSSs were functionalized through a stepwise process....

Polycations of main‐group elements have emerged as a significant research focus in recent years. Hypercoordinated dications having heavier pnictogens, such antimony (Sb) and bismuth (Bi), central atom been extensively studied due to their large atomic radii.

A practical arsenic halogenation of 9-arsafluorene, which can be safely and easily prepared from a cyclooligoarsine, was developed by using halogen sources such as iodine monochloride. The in situ 9-halogeno-9-arsafluorenes reacted with various nucleophiles to provide 9-arsafluorene derivatives. functional groups affected their emission properties the solid state through changes packing structure.

ABSTRACT Polyhedral oligomeric silsesquioxane (POSS) is a promising nanofiller for tuning properties of optically transparent polymer materials. On the other hand, traditional completely condensed POSS (CC‐POSS) has fundamental problem fabricating composite films; CC‐POSS high crystallinity due to its symmetrical structure, resulting in aggregation matrices. In this work, we have demonstrated that incompletely‐condensed (IC‐POSS), which an open‐cage can be well dispersed poly(methyl...
