Aromatik hidrokarbonların dedekte edilmesi için kaliksaren bazlı diamid kimyasal sensor çiplerinin geliştirilmesi

In the present work, a new macrocycle materials (SB77) was selected and Langmuir-Blodgett thin films of this compounds were examined for its vapor sensing capabilities against aromatic BTX hydrocarbons (benzene, toluene, xylene) through Quartz Crystal Microbalance (QCM) technique. accordance with aim, calix[4]arene LB prepared onto quartz crystal substrates. The characterization SB77 film performed nine layers fabricated crystal. frequency shifts mass changes monolayer these obtained as 32.35 Hz / per layer 2206.65 ng (8.32 mm-2), respectively. All QCM results indicated that chemical sensors exhibits high response, good sensitivity selectivity benzene at saturated or different concentrations than other hydrocarbon vapors. These calix [4]arene have been potential candidates organic applications simple low cost preparation room temperature.
