Abstract The design of square‐planar Pt(II) complexes with highly efficient solid‐state near infrared (NIR) luminescence for electroluminescence is attractive but challenging. This study presents the fine‐turning excited‐state properties and application a series isoquinolinyl pyrazolate that are modulated by steric demanding substituents. It reveals bulky substituents do not always disfavor metallophilic Pt···Pt interactions. Instead, π–π stacking among chelates, which fine‐tuned associated...
A new triplet–triplet annihilation-OLED exhibits deep-blue electroluminescence (CIE y ≈ 0.08) with a narrow full width at half maximum of 59 nm, high external quantum efficiency 6.43%, low turn-on voltage, and singlet exciton utilization 38%.
A novel Cd(II) supramolecular coordination framework containing mixed functionalized luminophore ligands, namely, [Cd(AS)2(phen)2]EtOH or 1 (where AS = 4-aminosalicylate, phen 1,10-phenanthroline, EtOH ethanol), was successfully synthesized as a solid-state luminescent sensor for the detection of amine vapors. The single-crystal X-ray diffraction analysis revealed that possesses three-dimensional (3D) enclosing ethanol molecule in lattice. structure is well-stabilized by various noncovalent...
Bismuth-based electrocatalysts for carbon dioxide (CO
The interplay between noncovalent interactions involving metal complexes may lead to the formation of aggregates (i.e., ground state dimers, trimers, n-mers, etc.), and this is often linked dramatic changes in their physical chemical properties as compared original isolated units. Dimers trimers can also be formed excited potential energy surfaces, i.e., excimers. Excimers are short-lived but characterized by different optical from those Understanding nature presence or not cooperativity...
A series of excited‐state intramolecular proton transfer (ESIPT)–aggregate‐induced emission (AIE) solid‐state fluorophores (TTHPI, PTHPI, and ATHPI) are reported as self‐absorption‐free emitters for electroluminescent (EL) devices. The molecules contain 2‐(2‐hydroxyphenyl)‐1,4,5‐triphenylimidazole an ESIPT core being double functionalized with AIE‐active luminogen tetraphenylethene hole‐transporting moiety (triphenylamine, N ‐(4‐phenyl)phenoxazine, or ‐(4‐phenyl)‐9,9‐dimethylacridine) to...
ESIPT derivatives functionalized with <italic>N</italic>-electron donating moieties show pure keto form emissions high solid-state fluorescence. As emitters, their OLEDs exhibit exceptionally brightness (41 292–44 820 cd m<sup>−2</sup>) and luminous efficiency (8.41–10.30 A<sup>−1</sup>).
Herein, three hydroxy-tetraphenylimidazole (HPI)-based fluorophores (HPI-TPA, HPI-PCz, and HPI-CzP) are designed synthesized by disubstituted HPI core with arylamine units of triphenylamine (TPA), phenyl carbazole (PCz), (CzP) at 3,5-positions the N-phenyl ring HPI, respectively. Their photophysical properties theoretically experimentally examined. HPI-TPA shows a hybridized local charge transfer (HLCT) excited state characteristic emits deep blue color via an HLCT mechanism, while both...

Synthesis of 5-hydroxymethylfurfural (5-HMF) from fructose in water over acids catalysts usually produces unsatisfactorily low yield and selectivity due to inevitable side reactions, i.e., rehydration condensation. Unprecedentedly, these complications the aqueous phase synthesis 5-HMF could be overcome by dendritic mesoporous silica particles (DMSNs). In hydrothermal reactions fructose, it discovers that synergy silanols mesopores transformed seemingly inert DMSNs into active leading an...
