A series of 1,3-distyrylbenzene compounds bearing different substituents at the 2-position have been synthesized and subjected to an oxidative photocyclization process. The 1,3-distyrylbenzene compounds substituted with chloro, alkylthio, and diphenylphosphino groups at the 2-position afforded dibenz[a,j]anthracene derivatives, whereas those bearing methyl, trimethylsilyl, dimethylamino, butoxy, and fluoro groups gave benzo[c]chrysene derivatives. The solubility of dibenz[a,j]anthracene in organic solvents was improved by the introduction of alkylthio groups.
A Fluorine-Containing Cryptand for the Complexation of Anions and the Utility of 19F NMR Spectroscopy for the Determination of Host-Guest Association

The first fluorine-containing cryptand F3-TREN 4 for the complexation of anions was prepared in the 3 + 2-condensation reaction of 2-fluoro-1,3-phthalaldehyde 3 with tris(2-aminoethyl)amine and subsequent reduction with NaBH4.Upon incorporation of anionic guests 4*6HClO4 experiences shifts of its 19F NMR resonances and thus demonstrates the advantages of studying host-guest association by 19F NMR spectroscopy. - Keywords: Macrocycles, 19F NMR Spectra, Fluorine, Anion Complexation
