To study the photoluminescence property of simple silver(I) coordination compounds constructed by 1,3,5-trithian ( 3S ), two new silver(I) polymers, namely, [Ag( 3S ) (9-AnCO 2 )] ∞ ( I , 9-AnCO 2  = anthracene carboxylate), and [Ag 2 ( 3S )(Ph 2 PO 2 ) 2 ] ∞ ( II , Ph 2 PO 2  = diphenylphosphinate), have been prepared and investigated by single-crystal X-ray diffraction (SXRD), fourier-transform infrared spectroscopy (FT-IR), thermal gravimetric analysis (TGA), solid-state UV–vis absorption spectra (SUV) and photoluminescence spectroscopy (PL). Polymer I represents an electroneutral one-dimensional polymer bridging only by 3S . Polymer II represents an electroneutral one-dimensional polymer co-bridging by 3S and diphenylphosphinate. Both polymers show bright emission at room temperature in the solid-state, cyan light for I, and green light for II . The Aggregation-induced Emission (AIE) phenomenon of II is also observed when gradually adding the weakly polar solvent (ether) to its CH 3 CN solvent. Our work shows that 3S is an excellent ligand for constructing new luminous coordination compounds.
