提出了球形主体分子的设计思想，把具有球形结构的分子柏木醇(1)、马钱子碱(2)、三乙烯二胺(1,4-二氮-二环[2.2.2]辛烷(3)作为主体分子，把酚类化合物，诸如苯酚(4)、邻甲苯酚(5)、间甲苯酚(6)、对甲苯酚(7)、对氯苯酚(8)和对硝基苯酚(11)等作为客体分子，进行了主客体分子相素作用实验，采用粉末X射线衍射、1^HNMR等分析手段确认了包结化合物的形成及主客体分子的摩尔比，摩尔比(H/G)分别为(1)+(4)1:1,(1)+(5)1:1,(1)+(6)1:1,(1)+(7)1:1,(1)+(11)1:2,(2)+(11)1:1,(3)+(4)1:2,(3)+(5)1:3,(3)+(6)1:2,(3)+(7)1:2,(3)+(8)1:2,(3)+(11)1:2,对典型包结化合物的单晶，诸如柏木醇和邻甲苯酚、马钱子碱和对硝基苯酚以及三乙烯二胺和对硝基苯酚，进行了四圆X射线衍射结构分析，结果表明，包结化合物的堆砌结构特征随主体分子的体积大小而改变，从隧道型如(1)+(5)和(2)+(11)转变为夹层型如(3)+(11)。用Nd:YAG激光测试晶体的SHG效应，结果表明，大部分包结物晶体具有非线性光学性质。

This paper introduces design idea of spherical clathrate hosts which uses cedrol(1), brucine(2), 1,4-diazabicyclo[2.2.2] octane (3) endowed of ball - shaped rigid molecular backbone as host molecules and phenol - type molecules such as phenol (4), o - cresol (5), m- cresol (6), p - cresol (7), 4-chrolophenol (8), 4-methoxyphenol (9), 4- hydroxylbenzaldehyde (10), 4-nitrophenol (11) and maleic anhydride (12) used as guest molecules. We have carried out inclusion experiment using these hosts with phenol - type compounds. The formation of inclusion compounds were confirmed by means of powder XRD, adn the molar ratios of inclusion compounds were determined by 1^H NMR, (1)+ (4) 1:1, (1)+(5) 1:1, (1)+(6)1:1, (1)+(7)1:1, (1)+(11)1:2,(2)+(11) 1:1, (3)+(5)1:2, (3)+(6)1:3, (3)+(7)1:2, (3)+(8)1:2,(3)+(9)1:2, (3)+(11)1: 2 as results . The single crystal structure of a few typical inclusion compounds was determined by X - ray diffraction analysis and showed that the variation of architectural structure characteristic of inclusion compounds depends on the volume size of the host molecules from channel type as with (1)+(5) and (2)+(11) to intercalate as with (3)+(11). The SHG effect of the inclusion compound crystals was inspected by Nd: YAG laser and the results showed that a mass of prepared inclusion crystals exhibits non-linear optical property.
