N, N′ - Ditritylurea and analogs as hosts in crystalline clathrate complexes: Synthesis and selectivity studies

Article abstract of DOI:10.1016/0040-4020(95)00432-8

Of 38 hosts, most of them new, designed on the 'wheel-and-axle' model, 24 formed clathrate complexes with small molecules; 95 new host/guest combinations are described (Table 6). Selectivity studies (Table 7) show, in some instances, substantial discrimin
