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.
