Hydrogen-bonding-induced Supramolecular Liquid Crystals and Luminescent Properties of Europium-substituted Polyoxometalate Hybrids
Eu-containing polyoxometalates, Na9EuW10O36, K11Eu(PW11O39)2, and K13Eu(SiW11O39)2, were electrostatically canned by a cationic surfactant, N-[12-(4 carboxylphenoxy)dodecyl]-N-dodecyl-N,N-dimethylammonium bromide, through the replacement of counterions, and the resulting surfactant-encapsulated polyoxometalate complexes were characterized in detail by elemental analysis as well as IR and NMR spect...

Self-assembly and Supramolecular Liquid Crystals based on Organic Cation Encapsulated Polyoxometalate Hybrid Reverse Micelles and Pyridine Derivatives
The controlled self-assembly of multi-components in one system represents the capability integrating intermolecular interactions and functions of components and is believed the key procedure leading to multifunctional materials finally. In pursuing this goal, we used a double-chain cationic surfactant with a benzoic acid group at the end of one tail to encapsulate Keggin-type polyanion clusters vi...

86. Inserting polyoxomolybdate cluster into poly(epsilon-caprolactone) to create a class of new heteropolymer: synthesis and supramolecular structures
In the present work, we report our work concerning the synthesis of heteropolymers of poly(-caprolactone)-polyoxomolybdate-poly(-caprolactone) using ring-opening polymerization (ROP) of -caprolactone monomer initiated by two hydroxyl groups attached on the two sides of a polyoxomolybdate cluster which was organically modified using pentaerythritols. Since the hydroxyl groups on polyoxomolybdate...

80. Correlation between Gel-forming Ability, Supramolecular Aggregates and Main-chain Conformation of Dendronized Polymer Gelators
Dendronized polymer (DP) gelators were prepared via complexation of a dendritic gelator of the poly(urethane amide) dendron, which contains an ionizing carboxyl group on the apexes, with three positively charged polyelectrolytes. All these complexes could form organogels in toluene, and their gel properties were studied through determination of their minimum gelation concentration and charac...

A New Level of Hierarchical Structure Control by Use of Supramolecular Self-assembled Dendronized Block Copolymers
In the present work, we show that by replacing, in a block copolymer, the linear polymer block with a dendronized polymer capable of participating in supramolecular interactions, the additional degree of freedom arising from the varying generation of the dendronized polymer allows engineering the self-assembly into unprecedented hierarchically ordered bulk structures. Not only does this allow cont...

Supramolecular Polyseudorotaxanes Formation between Star-Block Copolymer and a-Cyclodextrin: From Outer Block to Diblock Inclusion Complexation
A series of star-block poly(L-lactide)-b-poly(ethylene oxide) (SPLLA-b-PEO) copolymers were synthesized by ring-opening polymerization (ROP) and DCC chemistry. The inclusion complexes of SPLLA-b-PEO copolymers and a-cyclodextrin (a-CD) were prepared with two different methods. FTIR, 1H NMR, WAXD, DSC, and TGA indicate that a-CD only can be threaded onto PEO blocks in inclusion complexes of a-CD-SP...
