摘要

2,2,4,4,6,6-Hexakis (4-pyridylmethoxy) -2gamma~5,4gamma~5,6gamma~5,-cyclotriphosphazene (PyPN) and 1,4-anthracenedicarboxylic acid (DCA) formed polymeric supramolecules through hydrogen bonding between carboxyl and pyridyl groups. Two supramolecular self-assemblies were obtained: crystals 1 composed of PyPN/DCA = 1:2 from DMSO solution, and crystals 2 composed of PyPN/DCA = 1:3 from DMF solution. The former is monoclinic, space group P2_1 with a = 12.419 A, b = 24.10A, c = 20.794 A, beta = 93.53 deg, V = 6212 A~3, Z = 4. The X-ray analysis showed that the complementary hydrogen bonding occurs with two DCA molecules, one on each side of the phosphazene ring of PyPN, to give a novel assembly with polymeric structure. The self-assembly obtained from DMF solution seems to take a cylindrical structure composed of an alternating sequence of one PyPN and three DCA molecules and to be packed into a hexagonal arrangement, as suggested by X-ray diffraction data. These results and the inclusion behaviors of the solvent molecules into 1 and 2 are described.
