一些杯[4]芳烃（其中羧酸配位基团通过酚氢原子逐渐连接至下缘）的络合性质已通过电位滴定的方法在甲醇中与碱金属和碱土金属阳离子进行了测量。首先测定了这些化合物的酸碱特性。通常观察到的弱酸性可以通过分子内氢键的形成来解释。
The complexing properties of some calix[4]arenes in which carboxylic acid ligating groups have been progressively attached to the lower rim through the phenolic hydrogen atoms have been measured with alkali and alkaline-earth metal cations in methano by means of potentiometric titrations. The acid-base characteristics of these compounds were first determined. the weak acidities generally observed may be explained by the formation of intramolecular hydrogen bonding.
