Abstract:
Two new types of iodoargentate/iodobismuthate-based inorganic-organic hybrids were prepared and structurally characterized as {[Ln2(dpdo)(DMF)14](Ag12I18)}n (bpdo = 4,4′-bipyridine N,N′-dioxide, Ln = La (1), Nd (2), Sm (3)) and {[Ln(dpdo)(DMF)6](Bi2I9)2}n (Ln = La (4), Pr (5), Er (6)). These lanthanide-silver/bismuth heterometallic hybrids feature the novel templates of lanthanide-containing metalloviologen analogs, i.e., [Ln2(dpdo)(DMF)14]6+ (dimers for 1-3) and [Ln(dpdo)(DMF)6]n 3n- (1-D chains for 4-6). The (Ag12I18)n 6n- chains in 1-3 are constructed from edge-sharing Ag6I12 units, and (Bi2I9)3- clusters in 4-6 are defined by two face-sharing BiI6 otcahedra. The versatile weak interactions between metalloviologens and metal iodides stabilize the structures. Upon the introduction of metalloviologens, reversible thermochromism can be found in 1-6. Besides, electrodes with films of 1-6 exhibit effective and repeatable photocurrent responses. Finally, the possible thermochromism and photocurrent response mechanisms are also discussed. © 2018 the Partner Organisations.
