N,N'-DITRITYLUREA AND ANALOGS AS HOSTS IN CRYSTALLINE CLATHRATE COMPLEXES - SYNTHESIS AND SELECTIVITY STUDIES

摘要

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 discrimination between guests with similar structures. [References: 41]
