Abstract 0D organic‐inorganic Cu(I)‐based halides have gained significant attention due to their low toxicity, structural adjustability, and moderate fabrication conditions. However, it is still challenging explore stable efficient hybrid that phase transition tunable spectra for multifunctional photoelectric applications. Herein, two copper halides, green‐emissive (MTPP) 2 CuI 3 yellow‐emissive Cu 4 I 6 (MTPP = Methyltriphenylphosphonium), are successfully synthesized using a slow cooling method.

Achieving organic red/near infrared (NIR) phosphorescence at high temperatures is theoretically challenging because of the severe nonradiative transitions excited triplet states with low energy gaps. This study realizes bright and persistent red/NIR afterglow excellent high-temperature resistance up to 413 K via highly efficient (≈100%) resonance transfer (PRET) from rationally designed branched luminogens as donors dyes acceptors, coupled optimized aggregated structures. According systematic investigations, abundant internal cavities formed by in solid ensure dye loading space limitation, which can considerably suppress temperatures, promoting a stability.

Metal-organic frameworks (MOFs) have been proven promising ultralong room temperature phosphorescence (RTP) materials for anti-counterfeit due to their unique optical properties. However, it remains a major challenge achieve the desired phosphorescent properties limited regulatory methods and indistinct mechanism. Herein, coordination solvent second metal ion co-strategy is firstly proposed prepare seven robust heterometallic-organic (HMOFs) with two configurations: ZnMg/Ca-sol [sol = H2O, dimethylformamide (DMF), dimethylacetamide (DMA), formyldiethylamine (DEF)] ZnSr/Ba-H2O, exhibiting different RTP. The tunable lifetimes within 14.5-195.4 ms are achieved gradually by altering type of alkaline earth metals, solvent, hydrogen-bonding in HMOFs. Significantly, theoretical calculations reveal that promotion spin-orbit coupling heavy metals rigid constraint on skeleton result excellent balance between high quantum yield (ФP) long lifetime, especially ZnSr-H2O (6.8%, 195.4 ms). Depending wide-range tuning RTP great stability, HMOFs successfully applied spatial-time resolved anti-counterfeiting multi-level information encryption. This work may provide new approach designing target while resolving contradiction ФP lifetime.

Ligand-to-Ligand Charge Transfer Induced Red-Shifted Room Temperature Phosphorescence in Metal–Organic Frameworks

Journal of the American Chemical Society, Journal Year: 2025, Volume and Issue: unknown

Published: March 12, 2025

Research on room temperature phosphorescence (RTP) of metal-organic frameworks (MOFs) has been rapidly developed in recent years. However, it is still challenging to realize long-wavelength RTP (>580 nm). In this article, a new strategy proposed achieve the red-shifted through constructing dual-ligand MOFs. Different from single-ligand MOF, which lacks intermolecular interaction, MOF can build up stable donor-acceptor (D-A) relationship between two suitable simple ligands. Therefore, induced charge transfer (CT) process donor units acceptor framework decrease energy gap frontier orbitals, reducing excited state levels. Moreover, by modulating electron density and conjugation ligand, triplet states MOFs be further reduced. As result, centered at 588 nm successfully achieved MOF. Also, we clearly describe transporting path among ground, 1CT, 3CT states, revealing emitting mechanism RTP. This work not only extends D-A structure molecular level periodic but also solves problem achieving perspective.
