In this self-assembled entity both the cavity interaction of DCYQ6 included a nitrate anion and the portal interaction of the dipole carbonyls of DCYQ6 with sodium cations lead to form self assembled molecular capsules. The crystal structure of the entity shows a packing of the self assembled molecular capsules connected by hydrogen bonds of water molecules. CCDC: 271400.展开更多

The structure of the molecular bowl has been confirmed by the single crystal X-ray diffraction determination. It belongs to orthorhombic with space group of Pna21. The crystal unit cell parameters are: a=3.2108(6) nm, b=1.4742(3) nm, c=1.1516(2) nm, and V=5.4509(18) nm3, Dc=1.677 Mg·m-3, Z=4, F(000)= 2832, R=0.0551, wR=0.1568. CCDC: 290552.展开更多

There are two kinds of TMeQ6 A and B which formed molecular encapsulates with two silver ion lids in the self-assembled entities. One dimensional supramolecular tubes are formed from the encapsulates A, and two dimensional molecular sieves are formed from the encapsulates B, the tubes and the sieves stack together alternately in the self-assembled entities.
