【 摘 要 】

The potentiometric response of electrode no. 4 based on 1,3-bisbridged cofacial-calix[6]crown-5-ether (IV) gave a sub-Nernstian (45.0 mV/decade) response and the best detection limit (-log aep = 4.73) towards epinephrine. The responses are decreasing in the order of epinephrine > K+, dopamine > NH4+ > norepinephrine > Na+. It is remarkable that the proposed electrode shows the reasonable selectivity to epinephrine against other catecholamine neurotransmitters (dopamine and norepinephrine) as well as alkali metal ions.
