In recent years, nitro explosives have posed a threat to national security and human health due their hazard environmental contamination. The rapid effective detection of remains challenge. this work, new Schiff base ligand H2L was carefully designed successfully synthesized, = 1,1'-((1E,1'E)-(cyclohexane-1,4-diylbis (azanylidene)) bis (methylidene) (naphthalene-2-ol). Two coordination polymers, [Zn2L2]n [La(NO3)3 (H2L)2CH3OH]n, were constructed by solvothermal reaction. aforementioned polymers characterized X-ray, PXRD, TGA, FT-IR, the results demonstrated that Zn-CP La-CP exhibited one-dimensional chain structure two-dimensional reticular structure. Given excellent performance (CPs) in field fluorescence analysis sensing, sensing experiments conducted on explosives. experimental high selectivity sensitivity for 2,4,6-trinitrophenol (TNP) quenching, with limit 4 × 10-6 M. TNP even as low 0.78 M, quenching effect constants KSV 7.03 103 1.59 104 M-1. Through experimentation density functional theory calculations, observed can be attributed three mechanisms: photoinduced electron transfer, resonance energy electrostatic interactions between CPs NACs. Moreover, sensor-coated portable test strip devices fabricated easy on-site explosive.

Anion–π(–π) Interactions in Donor–Acceptor Hybrid Materials to Control Photochromism and Room-Temperature Phosphorescence

Inorganic Chemistry, Год журнала: 2025, Номер unknown

Опубликована: Март 20, 2025

Photochromic materials and room-temperature phosphorescence (RTP) are essential for applications in optoelectronics bioimaging. Organic–inorganic hybrid materials, particularly those exhibiting donor–acceptor (D–A) characteristics through supramolecular interactions, have shown significant potential to integrate both photochromic RTP properties. Among them, the anion–π π–π interactions been extensively studied; however, role of anion–π–π remains largely unexplored. This study investigated three naphthalenediimide-polyoxometalate (NDI-POM) hybrids: (H2DMAP-NDI)·(HPW12O40)·(NMP)2 (1), (HDMAP-NDI)2·(HPW12O40)·(NMP)2 (2), (HDMAP-NDI)2·(HPW12O40)·(NMP)7 (3), focusing on impact their The results indicate that 1 exhibits fastest photoresponse highest quantum yield, primarily driven by interactions. Hybrid 2, which involves shows slower photochromism lower yield due exciton localization nonradiative decay paths resulting from stacking. 3, characterized excessively strong is unstable nonemissive. provides valuable insights into offers a framework designing advanced photoresponsive with tunable properties diverse applications.
