| Popis: | Two new ternary coordination polymers (CPs), [Zn2(L)(DCTP)1.5(OH)]n (1) and {[Cd(L)(TBTA)]·H2O}n (2) (L = 1,3-bis(5,6-methylbenzimidazol-1-yl)propane, H2DCTP = 2,5-dichloroterephthalic acid, H2TBTA = tetrabromoterephthalic acid) were synthesized under hydrothermal conditions. 1 displays a square-lattice (sql) network formed by tetranuclear [Zn4(L)2(DCTP)6/2(H2O)2] complex groups, while in 2 the sql network is assembled from mononuclear complexes, both CPs are further extended into a 3D supramolecular framework by π–π stacking interactions. 1 and 2 exhibit promising photocatalytic activity toward the degradation of methylene blue (MB) under UV irradiation. Furthermore, 1 and 2 can be as efficient probes for detection of acetylacetone (acac) and Fe3+ ions based on luminescence quenching. |
