A new p-tert-butylthiacalix[4]arene derivative, C(72)H(68)N(4)O(4)S(4) x 2CH(2)Cl(2), has been synthesized and is comprised of one tetra-p-tert-butyltetrakis(2-cyanobenzyloxy)tetrathiacalix[4]arene and two dichloromethane molecules. The calix[4]arene molecule is centrosymmetric and adopts an unusual 1,2-alternate conformation via pi-pi interactions between adjacent cyanophenyl rings on the lower rim of the parent thiacalix[4]arene system.
一种新的对叔丁基硫杂杯[4]芳烃衍生物C(72)H(68)N(4)O(4)S(4)·2CH(2)Cl(2)已被合成，它由一个四对叔丁基四（2-氰基苄氧基）四硫杂杯[4]芳烃和两个二氯甲烷分子组成。杯[4]芳烃分子是中心对称的，通过母体硫杂杯[4]芳烃体系下缘相邻氰基苯环之间的π-π相互作用，呈现出一种不寻常的1,2-交替构象。
