This thesis reports the synthesis of organic supramolecules containing 1,3,5-triazine and piperazine units. We used acyl amine groups at 1 and 3 positions of the benzene ring as the starting groups to react with nitrogen-containing compounds or cyanuric chloride for preparing molecules with different core structures and different peripheral functionalities to control their stacking in the solid state. Thus a series of organic supramolecules were obtained by H-bond self-assembling interaction and then a representing sample was studied in the solid state by single crystal structure determination.
