In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Tripodal 4-Pyridyl-Derived Host Ligands and Their Metallo-Supramolecular Chemistry: Stella Octangula and Bowl-Shaped Assemblies, published in 2010-01-18, which mentions a compound: 217192-22-8, mainly applied to palladium cyclotriveratrylene derivative preparation bowl shaped assembly; crystal structure cyclotriveratrylene cyclotriguaiacylene derivative palladium complex, Recommanded Product: (4-(Pyridin-4-yl)phenyl)methanol.
The synthesis of five new cyclotriveratrylene derivatives with 4-pyridyl side arms is reported, along with the crystal structures of three of these. Three ligands with extended 4-pyridylphenyl side arms and a ligand derived from cyclotriphenolene form [Pd6L8]12+ stella octangula assemblies using diffusion-ordered spectroscopy NMR and electrospray MS techniques. This confirms the generality of the stella octangula assembly, providing that the ligand arms show a degree of rigidity. The more flexible ether-linked ligand tris(4-pyridylmethyl)cyclotriguaiacylene forms a smaller [Pd3L4]6+ bowl-shaped assembly in the solid state and in solution The previously reported ligand tris(4-pyridylmethylamino)cyclotriguaiacylene forms a similar assembly in solution
Although many compounds look similar to this compound(217192-22-8)Recommanded Product: (4-(Pyridin-4-yl)phenyl)methanol, numerous studies have shown that this compound(SMILES:OCC1=CC=C(C2=CC=NC=C2)C=C1), has unique advantages.
