Improving electron harvesting Small metal nanostructures generate electrons from light by creating surface plasmons, which can transfer “hot electrons” to a semiconductor. The efficiency of this process, however, is often low because electron-electron scattering. Wu et al. demonstrate pathway that allows the plasmon directly excite an in strongly coupled semiconductor acceptor (see Perspective Kale). Cadmiun selenide nanorods bearing gold nanoparticles on their ends damped plasmons via...
Near-infrared (NIR) fluorophores absorbing maximally in the region beyond 800 nm, i.e., deep-NIR spectral region, are actively sought for biomedical applications. Ideal dyes bright, nontoxic, photostable, biocompatible, and easily derivatized to introduce functionalities (e.g., bioconjugation or aqueous solubility). The rational design of such remains a major challenge. Silicon-substituted rhodamines have been successful bioimaging applications red region. longer-wavelength...
The intermediacy of alkoxy radicals in cerium-catalyzed C–H functionalization via H-atom abstraction has been unambiguously confirmed. Catalytically relevant Ce(IV)–alkoxide complexes have synthesized and characterized by X-ray diffraction. Operando electron paramagnetic resonance transient absorption spectroscopy experiments on isolated pentachloro Ce(IV) alkoxides identified as the sole heteroatom-centered radical species generated ligand-to-metal charge transfer (LMCT) excitation....
The shortwave infrared (SWIR) spectral region beyond 1200 nm offers optimal tissue penetration depth and has broad potential in diagnosis, therapy, surgery.

EC7 absorbs/emits maximally at 1204/1290 CH2Cl2 exhibits an unparalleled molar absorptivity 3.91 × 105 cm–1 M–1 high transparency to light 400–900 nm. It also exhibited resistance toward both photobleaching symmetry breaking due its...

Taking advantage their unique dual stimuli‐responsiveness towards solvent and anion, resultant [2]rotaxanes reveal both VIE switchable circularly polarized luminescence (CPL). Attributed to formation...
The shortwave infrared (SWIR) region is an ideal spectral window for next-generation bioimaging to harness improved penetration and reduced phototoxicity. SWIR activity may also be accessed via supramolecular dye aggregation. Unfortunately, development of aggregation remains challenging. We propose a crystal-aided aggregate synthesis (CAASH) approach introduce layer rationality the J-aggregate successful water-soluble JV-aggregate with bisbenzannulated silicon rhodamine scaffold (ESi5)....

An efficient photocatalyst should maximize utilization of sunlight and minimize recombination photogenerated electron–hole pairs. Thus, searching for a simple approach to develop low-cost photocatalysts improve the ratio boost charge carrier lifetime is very important challenging. In this article, anchoring Cu2O nanoparticles (NPs) in situ on nitrogen-doped porous carbon yolk–shell cuboctahedral (CNPC) framework has been successfully carried out by direct derivation from...

A critical step involved in many applications of one-dimensional seeded CdSe@CdS nanorods, such as luminescent solar concentrators, optical gains, and photocatalysis, is the localization excitons from light-harvesting CdS nanorod antenna into light-emitting CdSe quantum dot seed. We report that rod-to-seed exciton efficiency decreases with rod length but independent band alignment between seed rod. This universal dependence can be well modeled by competition diffusion to trapping on finding...
The fluorescence-phosphorescence dual solvoluminescence (SL) of water-soluble metal nanoclusters (NCs) at room temperature was successfully achieved by a simple solvent-stimulated strategy. strong interaction between carboxylate ligands and the core nanoscale interface not only induces rigid conformations carbonyl groups but also affords perfect cluster that acts as an exact chromophore NCs for aggregation-induced emission (AIE) mechanics. clustering bearing on polymer backbone chain is...
Abstract The preparation of fluorescent discrete supramolecular coordination complexes (SCCs) has attracted considerable attention within the fields chemistry, materials science, and biological sciences. However, many challenges remain. For instance, fluorescence quenching often occurs due to heavy-atom effect arising from Pt(II)-based building block in Pt-based SCCs. Moreover, relatively few methods exist for tuning emission wavelength Thus, it is still challenging construct SCCs with high...
