| Popis: | Two anion-directed Cu(I) coordination polymers (CPs), namely, [Cu2(TMBP)2(μ-CN)(I)·3.5H2O]n (1, TMBP = 3,3′,5,5′-tetramethyl-4,4′-bipyrazole) and [Cu2(TMBP)2(μ-SCN)(μ-CN)]n (2), were synthesized through solvothermal method and characterized by single crystal and powder X-ray diffraction, elemental analysis. 1 is a 3-dimension framework with nanocavity and (42 · 63 · 8) topology while 2 is a 2-dimension network with 3-fold penetration and (62 · 10)(6.6) topology, the difference in structure being related to the anions (I− or SCN−) included in precursor solution. Furthermore, 1 exhibits strong blue emission when excited at 315 nm, which should be resulted from I to Cu(I) charge transfer; however, no obvious luminescence was observed in case of 2. This work emphasizes a strategy of anion-directed synthesis of CPs for tuning photoluminescent property. |
