摘要:

A supramolecular mesophase was prepared from molecular recognition directed self- assembly of two complementary molecular components, namely 5-(4-dodecyloxy- benzylidene)-2,4,6-(1H,3H)-pyrimidinetrione and 4-amino-2,6-didodecylamino-1,3,5triazine. Differential scanning calorimetry measurements indicate a mesophase having liquid crystalline properties. Infrared studies suggest that not only hydrogen bonds but also pi-aromatic stacking and van der Waals interactions direct the formation of the mesophase.
