Abstract

The project suggests the development of methodology for immobilization of uryl macrocycles (bamboo[n]uril, hemi-cucurbit[n]uril, and biotin[n]uril) on the surface of electrodes and quartz pizoelectric crystals. These are meat for the assembly of ion-selective electrodes for fluoride ions in treated water, and piezoelectric sensors to be tested later for gases such as halogen and CO2. It seeks a method capable of producing films on gold, platinum, glassy carbon, and ITO and FTO- type electrodes that are thin, ordered, resistant to leaching, and that can interact with small che- mical species in solution and in the gas phase.
