| Popis: | Thin calix[n]arene (n = 4 and 8) films are directly deposited using a thermal evaporating method on the silica insulator of EOS structures which are tested by an AC capacitance method. A selective response of 59.2 and 3.8 mV respectively per decade is observed for sodium and cobalt using calix[4]arene. For the detection of cobalt ions, the response was significantly improved up to 22.2 mV/pCO using calix [8] arene. The response of the structures remains the same after 3 months storage in water. |
