family of host molecules where the molecular axis of usual ‘wheel-and-axle’ compounds is replaced by aromatic units is described. These diol hosts form crystalline inclusions with a variety of uncharged organic molecules mainly of a polar nature (53 different copecies). The formation and stoichimetry depend in a systematic manner on structural parameters of the host allowing these hosts to be more
描述了一个新的宿主分子家族,其中常用的“轮轴”化合物的分子轴被芳族单元取代。这些二醇主体与主要为极性性质的多种不带电荷的有机分子形成结晶内含物(53种不同的混合物)。形成和化学计量系统地取决于宿主的结构参数,从而使这些宿主比母体化合物更具选择性。非羟基类似物不充当宿主分子。研究了主体化合物2和低效化合物9的两种多晶型物的晶体结构。晶体数据:2(多晶型物α 1),单斜晶,c ^ 2 / Ç,一个= 16.827(2),b= 15.212(3),c= 10.708,β= 97.01(1)°,V= 2721 3,Z= 4;2(多晶型物α 2),三斜晶系,P,一个= 8.807(2),b = 10.687(6),C ^ = 16.263(3)埃,α= 100.97(3)°,β = 91.47(2)°,γ = 113.02(3)°,V = 1375埃3,ž = 2; 9,单斜,P 2 1 / n,a
