Abstract: Disclosed are compounds with the following structure (Formula (I)) where (Formula (II)) or (Formula (III)), X is an anion (e.g., a biologically suitable anion, such as, for example, chloride, iodide, and the like). Y is NH, NR10, or CR11R12. Z is a heteroatom (e.g., O, S, or Se). R and R1 are independently chosen from methyl, ethyl, propyl (e.g., n-propyl, isopropyl), butyl (e.g., n-butyl, isobutyl, tert-butyl), and the like, and combinations thereof. In various examples, R and R1 are not both oxygen atoms (such that an —NO2 is formed). R2 and R3 are independently chosen from methyl, ethyl, propyl (e.g., n-propyl, isopropyl), butyl (e.g., n-butyl, isobutyl, tert-butyl), and the like, and the like, and combinations thereof. R4, R5, R6, R7, R8, R9, R10, R11, and R12 are independently chosen from hydrogen, alkyl groups (e.g., methyl, ethyl, propyl (e.g., n-propyl, isopropyl), butyl (e.g., n-butyl, isobutyl, tert-butyl)), and the like, and combinations thereof.
