通过应用两个供体-受体基序分子,(吡啶-4-基)-5,10-二氢吩嗪(L1)和10,10'-二(吡啶-3-基)-10H,10 ′ H-9,9 ′-螺吖啶(L2)为配体,CuI/AgCF_3CO_2为金属盐,合成了三种配位聚合物:{Cu_4(L1)_2I_4}(CP_1),{Cu(L2)I·CHCl3}(CP2)和{Ag(L2)CO2CF3·CHCl3}(CP3)。X射线晶体学分析表明,三种配位聚合物都具有一维(1D)线性链,这些链由分子盒状单元组成。与两种配体的低光致发光量子产率(PLQY)相比,三种配位聚合物CP 1、CP 2和CP 3在室温下具有更强的光致发光,PLQY分别为15%、46%和34%。在室温下,CP 1和CP 2的PL发射都是由于有效的系间跃迁(ISC)而产生的,寿命均在5 μ s左右的快速磷光。同时,值得注意的是,CP 3在室温下表现出热激活延迟荧光(TADF)发射。
By applying two donor-acceptor motif molecules, 5,10-di(pyridin-4-yl)-5,10-dihydrophenazine (L1) and 10,10'-di(pyridin-3-yl)-10H,10'H-9,9'-spiroacridine(L2), as ligands and CuI/AgCF3CO2as metal salt, we synthesized three coordination polymers, namely, {Cu4(L1)2I4} (CP1), {Cu(L2)I·CHCl3} (CP2) and {Ag(L2)CO2CF3·CHCl3} (CP3). X-ray crystallographic analysis revealed that three coordination polymers all feature one-dimensional (1D) linear chains which are consisting of molecular boxlike units. In comparison with low photoluminescence quantum yield (PLQY) of two ligands, three coordination polymers,CP1,CP2andCP3, present more intense photoluminescence with PLQY of 15%, 46% and 34% at room temperature respectively. The PL emission ofCP1andCP2at room temperature could be attributed to the fast phosphorescence with lifetime both around 5 μs due to effective intersystem crossing (ISC). Whilst, it is worth noting thatCP3exhibit thermally activated delayed fluorescence (TADF) emission at room temperature.
