摘要:

The process of molecular recognition directed self-assembling between two complementary molecular components. 5-(4-dodecyloxybenzylidene)-2,4,6-(1H, 3H)-pyrimidinetrione (B) and 4-amino-2,6-didodecylamino-l,3,5-triazine (M),was studied using fluorescence spectroscopy. It was found that it took more than 1200 h for this process to reach the equilibrium.This means that there must be other kinds of noncovalent interactions besides hydrogen bonds.This system has a positive cooperativity and B is proved to be as both the fluorescence probe and molecular components of the self-assembling.
