Molecular oxygen activation has always been a difficult issue and challenge in heterogeneous photocatalytic aerobic oxidations due to the kinetically persistent or spin-forbidden nature of O2. In this work, highly delocalized interpenetrated 3D MOF photocatalyst with high stability, Zn-TACPA (H3TACPA = tris(3-carboxybiphenyl)amine), based on vinyl-functionalized triphenylamine bipyridine ligands fabricated employed as reactive species (ROS) generator catalyze photooxidative CDC/aromatization...
A new ABW-type luminescent metal-organic framework (MOF) namely (H3O)[Zn2L(H2O)]·3NMP·6H2O (1), constructed with eco-friendly Zn2+ and the multicarboxylate intraligand (LH5) was designed, synthesized fully characterized by X-ray single-crystal diffraction, steady-state absorption emission spectroscopy, SEM observations. The MOF-based suspension sensor 1 (NMP) demonstrated high sensitivity to low-concentration pesticides of chlorothalonil (CTL), nitrofen (NF), trifluralin (TFL),...
Self-assembly reactions of Zn2+ and L5– (H5L = 2,5-(6-(4-carboxyphenylamino)-1,3,5-triazine-2,4-diyldiimino) diterephthalic acid) lead to the formation two new ABW-type zeolitic metal–organic frameworks (Z-MOFs): (Me2NH2)[Zn2L]·3.5DMF (1) (Me2NH2)[Zn2L(H2O)]·2DMF·8H2O (2) (DMF N,N-dimethylformamide). They are first Z-MOFs which built same pentacarboxylate ligand metal ion but have configurations channel shapes (distorted honeycomb- herringbone-shaped channels for 1 2 respectively). can...
Herein we report the first two (5,5)-connected isomeric frameworks, namely, (Me2NH2)[Zn2L(H2O)]·3.5DMF (1) and (Me2NH2) [Zn2L(H2O)]·6DMF·4H2O (2) (DMF = dimethylformamide, H5L 5,5′-(6-(4-carboxyphenylamino)-1,3,5-triazine-2,4-diyldiimino) diisophthalic acid), obtained via assembly reactions between Zn2+ a semi-rigid pentacarboxylate ligand (L5−). Single-crystal X-ray diffraction analyses reveal that both compounds are three dimensional metal–organic frameworks (MOFs) built of same...
Three Ir(iii) complexes IrC1, IrC2, and IrC3 substituted with 4-(diphenylamino)phenyl (TPA), 4-(9H-carbazol-9-yl)phenyl (Cz1), 9-phenyl-9H-carbazol-3-yl (Cz2) moieties were prepared fully characterized as phosphorescent emitters. In comparison Ir(ppy)3, introduction of TPA, Cz1, Cz2 strongly improved the oxygen sensitivities IrC1-IrC3. Short-decayed IrC1 I 0/I 100 168.6 K app SV 202.2 bar-1 in THF exhibited highest sensitivity for oxygen. TPA Cz caused remarkable collision radius variations...
Three triphenylamine (TPA) substituted cyclometalated Ir(iii) complexes IrA1, IrA2, and IrA3 based on Ir(ppy)3 were synthesized applied as phosphorescent probes for the monitoring of molecular oxygen. The phosphorescence intensity all in tetrahydrofuran (THF) was gradually quenched with an increase oxygen concentration. TPA substituents meta-position 2-phenylpyridine (IrA1-IrA3) improved sensitivity complexes. showed highest THF a K app SV 204.8 bar-1 limit detection (LOD) 0.27 mbar....
