V originále

The formation of a highly stable inclusion complex between 2,7-dimethyldiazapyrenium (Me2DAP2+) and the cucurbit[8]uril host (CB8) was demonstrated by X-ray crystallog.; MALDI-TOF mass spectrometry; and 1H NMR, electronic absorption, and emission spectroscopy. The equil. assocn. const. was detd. to be 8.9(ą0.2) 105 L mol-1 from UV-visible data and 8.4(ą1.5) 105 L mol-1 from fluorescence data. The Me2DAP2+CB8 inclusion complex acted as a host to bind compds. contg. arom. p-donor moieties (D), such as catechol and dopamine. This point was demonstrated by 1H NMR spectroscopy, and electrochem. and emission measurements. Fluorescence detection of the Me2DAP2+DCB8 ternary complexes was evident in aq. soln. and on the surface of silica particles, to which fluorescent diazapyrenium units had been covalently immobilized.

Česky

Tvorba vysoce stabilního inkluzivního komplexu mezi 2,7-dimethyldiazapyreniem (Me2DAP2+) a cucurbit[8]urilem(CB8) byla prokázána pomocí rengenové krystalografie, MALDI-TOF hmotnostní spektoskopie, elektronové absorbční a emisní spektroskopie.
