Designing and developing novel photochromic materials with additional functions such as photothermal conversion photocatalysis are challenging but meaningful objectives. Crystalline naphthalenediimide (NDI)-based hybrids an attractive class of multifunctional fast-response photoinduced electron transfer charge separation properties. They promising photocatalysts. Herein, a hybrid material, EuPMo11O39(L)1.5(H2O)2]·DMA (EuMo-NDI) (L = N,N'-di(1-oxido-4-pyridyl)-1,4,5,8-naphthalenediimide), was prepared solvothermal method, integrating photoactive NDI derivative Eu-substituted polyoxometalate. EuMo-NDI exhibits 0D structure sensitive behavior under UV-vis light irradiation due to between its components. The colored sample demonstrated efficient near-infrared the strong absorption photogenerated radical anion NDI•- mixed valence heteropoly blue in region. Meanwhile, is easily excited presence donors form species, which can activate inert O2 superoxide O2•-. exhibited high photocatalytic activity for C-3 thiocyanation indoles mild conditions using white driving force. This work provides effective avenue design photocatalysts platforms.

The synthesis of two three-dimensional coordination frameworks [CdX2(TPA)] (X = Br for 1 and I 2) has been achieved through the assembly tri(pyridine-3-yl)amine (TPA) with cadmium halides. compounds are isostructural, both fabricated from infinite linkage Cd2+ TPA molecules, halide anions serving as μ2-bridging terminally coordinated species. Photoluminescence properties polymers have thoroughly examined, revealing room-temperature phosphorescence unique decay lifetimes. Remarkably, a yellow glow is samples owing to heavy atom effects. A comprehensive structure–property analysis, complemented by theoretical calculations, conducted elucidate mechanisms underlying fluorescence phosphorescence. Furthermore, photochromic behavior Cd–Br-based solid, which based on an electron transfer process, also investigated.

An Activatable NIR Yb₄Zn₂ Cluster for the Detection of Quercetin: Analysis of Host–Guest Interaction and Sensing Mechanism

Inorganic Chemistry, Journal Year: 2025, Volume and Issue: unknown

Published: March 10, 2025

A rod-like Yb4Zn2 nanocluster was constructed, which could be an activatable NIR probe for quercetin, with a short response time (5 s) and low detection limit (0.75 μM). Theoretical simulations reveal that strong π···π interactions hydrogen bonding result in good orbital overlap charge transfer from quercetin to the cluster.
