抄録

Crown-bridged calix[4]quinones (<B>5</B> and <B>6</B>) were synthesized from calix[4]crown (<B>2</B>). The ion-selective electrodes prepared from <B>5</B> or <B>6</B> still retained high selectivity for Na<SUP>+</SUP> against K<SUP>+</SUP> (>10<SUP>3</SUP>). For protein solution samples the electrode prepared from <B>2</B> showed a large phase divergence whereas those prepared from <B>5</B> or <B>6</B> were much more stable in protein solution. The difference is attributed to the less hydrophobic nature of <B>5</B> and <B>6</B> which strongly influences the protein adsorption onto the membrane surface.
