Supramolecular Chemistry of Multinuclear Zinc(II) Complexes in Aqueous Solution

[Supramolecular chemistry of multinuclear zinc(II) complexes in aqueous solution].

We report novel supramolecular polyhedrons formed by three-dimensional self-assembly of multinuclear zinc(II)-12-membered tetraamine (= cyclen = 1,4,7,10-tetraazacyclododecane) complexes with potentially multidentate ligands such as cyanuric acid (CA) and trithiocyanuric acid (TCA) in aqueous solution. Two new supermolecular frameworks were isolated by self-assembly of a tris (Zn(2+)-cyclen) (Z...

Supramolecular Complexes and Supramolecular Catalysts Formed by Molecular Assembly of Multinuclear Metal Complexes in Aqueous Solutions

New supramolecular trigonal prisms from zinc(II)- 1,4,7,10-tetraazacyclododecane (cyclen) complexes and trithiocyanurate in aqueous solution.

The multiple bonding between multinuclear zinc(II)-1,4,7,10-tetraazacyclododecane (cyclen, a 12-membered tetraamine) complexes and multidentate ligands is an effective method for constructing supramolecular complexes having well defined and distinct structures in aqueous solution. Herein we present examples of supramolecular D(3h) prisms formed by self-assembly of linearly dimeric or trimeric z...

Aqueous Solution Surface Chemistry of Carbon Nanotubes

Supramolecular self-assembly of multiblock copolymers in aqueous solution.

A unique pH-dependent phase behavior from a copolymer micellar solution to a collapsed hydrogel with micelles ordered in a hexagonal phase was observed. Small-angle neutron scattering (SANS) was used to follow the pH-dependent structural evolution of micelles formed in a solution of a pentablock copolymer consisting of poly((diethylaminoethyl methacrylate)-b-(ethylene oxide)-b-(propylene oxide)...
