Of 38 hosts, most of them new, designed on the ‘wheel-and-axle’ model, 24 formed clathratecomplexes with small molecules; 95 new host/guest combinations are described (Table 6). Selectivitystudies (Table 7) show, in some instances, substantial discrimination between guests with similar structures.

of the corresponding easily accessible cyanohydrin derivatives in methanolic sulfuricacid. Facile desymmetrization, monofunctionalization, and efficient chain-elongation coupling of OEGs further enable the incorporation of OEGs to α-hydroxy acids in a simple and efficient manner. At the end, synthesis of allyloxy lactic acid indicates that an alkene group is also compatible with the developed method

formation is likely to be mediated by hydrophobic interactions between the triphenylmethyl moieties and alkyl chains. Possible self-assembled packing arrangements in the gel state for 1,8-bis(trityloxy)octane and (hexadecyloxymethanetriyl)tribenzene are presented. Results from this study strongly indicate that triphenylmethyl group is a promising gelling structural unit which may be further exploited
