研究了中性1,4-二卤丁烷与简单柱[5]芳烃的络合反应。结果表明，相互渗透的配合物形成，其中色散相互作用主导了配合物的稳定性。通常，1,4-二碘丁烷与乙基[5]芳烃的结合强度最强[K-a = (1.0 + 0.1) × 10(4) M-1]，是1,4-二氟丁烷的120倍。
The complexation of neutral 1,4-dihalobutanes with simple pillar[5]arenes was investigated. The results indicate the formation of interpenetrated complexes, where the dispersive interactions dominate the complex stability. Typically, 1,4-diiodobutane displays the strongest binding strength with ethylpillar[5]arene [K-a = (1.0 + 0.1) x 10(4) M-1], up to 120 fold as compared with 1,4-difluorobutane.
