STUDY ON SELF-ASSEMBLING MOLECULAR-COMPLEXES THROUGH HYDROGEN-BONDING

A self-complementary hydrogen-bonding recognition unit-2,5-bis(alkylam ino)-1,4-benzoquinone has been synthesized and studied. The formation of hydrogen bond in both solid and solution state has been further inv estigated by means of FTIR, H-1 NMR and UV-visible spectra, as well as X-ray diffraction. It can be concluded from the obtained results that the molecular complexes of this kind of compounds have a ribbon-like backbone which plays an important role in keeping the layer supramolec ular structure.
