Structurally different complex bismuth iodides with 1D anionic frameworks were designed and explored as semiconductor materials for photovoltaic devices.
Reactions of BiI 3 , I 2 , and iodide salts of two different pyridinum cations result in the formation of the novel iodine-rich iodobismuthates(III) (1,3-MePy) 4 {[Bi 4 I 16 ](I 2 )} (1) and (1-MePy){[BiI 4 ](I 2 ) 0.5 ) (2), where the halometalate anions are connected by diiodine linkers into one-or two-dimensional supramolecular structures. Both complexes reveal narrow optical band gaps and fairly high thermal stability, favoring their potential use in photovoltaic devices.
Reactions of TeO2and Br2in concentrated HBr in the presence of various organic cations resulted in the formation of one-dimensional supramolecular polymers with the structure cation2{[TeBr6](Br2)}.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
