A series of substituted 12-sulfonium zwitterions 1[n] and one example of a 1-sulfonium analogue 2[5]a were prepared in four steps. Derivatives 1[n] exhibit rich crystalline polymorphism and a high-temperature SmBcry phase stabilized by dipolar intera

Antipodal substitution of the [closo-1-CB11H12](-) anion with a 4-pentylquinuclidinium fragment and alkyl groups in positions C(1) and B(12) gave polar zwitterions 1[n] and 2[n]. The molecular structure of 1[5] was established using X-ray diffraction

Intramolecular electronic interactions were investigated in five series of 12-, 10-, and 6-vertex closo-boranes and hydrocarbons (benzene, acetylene, bicyclo[2.2.2]octane, and cubane) substituted with triple-bonded groups Y≡Z (C≡CR, C≡N, C≡O,

A triphenylsilyl group is used as an auxiliary in the synthesis of heterodisubstituted p-carboranes via triphenylsilyl-p-carborane (1). The preparation of 1 is statistical, but with recovery of the starting p-carborane, the effective conversion to 1

Water soluble, metallo-pthalocyanine (MPc) near-IR fluorophores were designed, synthesized, and evaluated as highly stable and sensitive reporters for fluorescence assays. Their conjugation to oligonucleotides was achieved via succinimidyl ester-amin
