摘要
The present disclosure provides chalcogenopyrylium compounds, composite nanostructures comprising the chalcogenopyrylium compounds, and methods of using the compounds and/or composite nanostructures. For example, composite nanostructures comprising the chalcogenopyrylium compounds are used in imaging applications. The present disclosure provides chalcogenopyrylium compounds having the following structure where each E is, at each occurrence in the compound, independently charged or neutral and is independently selected from S, Se, 0, or Te, wherein at least one E is S or Se; each R1 is, at each occurrence in the compound, independently selected from the group consisting of —H, Ci-s alkyl group, halo group, —CN, aryl group, and heteroaryl group and adjacent R1 groups can combine to form C5ss aryl groups, each R2 is, at each occurrence in the compound.
