摘要
This work presents the comparative study of the spontaneous adsorption of cucurbit[6]uril and cucurbit[7]uril on gold by means of atomic force microscopy. A faster cucurbit[6]uril adsorption was not achieved by the use of a cucurbit[6]uril solution with sodium salts to increment its solubility than by the treatment with a saturated one in water. However, sodium ions promoted the cucurbit[6]uril polymerization on the previously adsorbed layer. The electrode reaction of hydroquinone became irreversible when a cucurbit[6]uril modified gold electrode was used. Cucurbit[7]uril adsorption was faster than for the smaller homologue and multilayers were generated too with high adsorption times.
