Based on the complementary structure of the lipid bearing barbituric acid and 2,4,5,6-tetraaminopyrimidine, regular and laminar.molecular aggregates were formed simultaneously in water,and their structures were confirmed by use of SEM and X-ray diffraction. There is a thermal phase transition corresponding to about △H=12.2kJ/mol in their DSC curves,which disappears in the cooling and the following heating and cooling runs. Combined the data of IR spectra,this transition is due to the hydrogen-bond in the aggregate,and thus the results obtained support the concept of hydrogen-bond-directed formation of molecular aggregate.By use of these types of heading compounds as anchor molecules,a new kind of funciton supermolecular materials is greatly anticipated.
