The realization of multifunction in one bulk material is fascinating for developing a new generation of devices. Quaternary phosphorus salts were seldom utilized as templates in haloargentate systems, and the hybridization of alkyl(triphenyl)phosphonium with halometallate will be a good strategy for the development of multifunctional material, especially for biological material. Under the template of (triphenyl)phosphonium-based quaternary phosphorus salts with different spacer lengths (n=2, 3, 4), three bromoargentate hybrids were constructed via the solution method, ie, (1,2-DBTPP)(Ag Br ) ( ), {(1,3-DBTPP) (Ag Br )]∙CH CN∙H O} ( ), and {[(1,4-DBTPP)(Ag Br )](CH CN) ∙H O} ( ) (1,2-DBTPP =ethane-1,2-diylbis (triphenyl)phosphonium, 1,3-DBTPP =propane-1,3-diylbis (triphenyl)phosphonium, 1,4-DBTPP =butane-1,4-diylbis (triphenyl)phosphonium)). The (Ag Br ) chain in is a new type of 1-D bromoargentate chain constructed from cubane-like Ag Br nodes, AgBr tetrahedrons and AgBr triangles. Interestingly, by elongating spacer n from 2 to 4, argentophilicity interactions are weakened, and the hydrogen bonds are strengthened. Consequently, their water stabilities and photocurrents are improved, in which the Ag-4d/Br-4p to π* anti-bonding orbital of the quaternary phosphorus transfer is facilitated. Furthermore, the greenish blue emissions can be detected. Finally, high inhabitation rates against and can be observed in and . In all experiments, by elongating the spacer lengths of quaternary phosphorus salts, multifunctions were integrated in the quaternary phosphorus/bromoargentate hybrids, including greenish blue luminescence, repeatable photocurrent responses and durable antimicrobial activities with enhanced water stability. This work could provide a theoretical guide for the design of new biologically multifunctional materials.
