Incorporating functional organic linkers into supertetrahedral chalcogenolate cluster-based materials is an effective synthetic strategy to expand structural diversity and generate tunable optical and photoelectric properties arising from synergistic effects. Herein, a mixed ligand engineering approach was adopted to design a supertetrahedral cluster-based assembled material [(Cd 6 Ag 4 (SPh) 16 (TPPA)(BPE) 0.5 )·2DMF] n (denoted as SCCAM-3) with a 2D bilayer architecture and broader visible-light absorption. Interestingly, SCCAM-3 demonstrates a long-lived afterglow at 83 K and efficient photocatalytic activity for degrading tetracycline in water. Using a mixture of conjugated TPPA and BPE linkers, this work achieved a 2D bilayer supertetrahedral chalcogenolate cluster-based assembled material, which exhibited a long-lived afterglow and efficient photocatalytic activity.
