A chemically reactive hybrid diblock polypeptide gelator poly(ethylene glycol)-block-poly(dl-allylglycine) (PEG-b-PDLAG) is an exceptional material, due to the characteristics of thermo-reversible organogel formation driven by the combination of a hydrophilic polymer chain linked to a racemic oligomeric homopeptide segment in a range of organic solvents. One-dimensional stacking of the block co...
Fullerene (C(60))-rich and photoconductive flowerlike supramolecular assembly was constructed from self-organization of pyridine substituted C(60) by a facile drop-casting method.
A general and simple method was presented for preparing supramolecular hydrogels to deliver anticancer drugs. In this system, hydrophobic anticancer drug doxorubicin (Dox) was loaded into poly(ethylene glycol)-b-poly(ε-caprolactone) (PEG-b-PCL) amphiphilic block copolymer micelles by hydrophobic interaction. The drug loaded micelles were then mixed with α-cyclodextrin (α-CD) solution to generat...
Supramolecular aggregates can be aligned in solution using a magnetic field. Because of the optical anisotropy of the molecular building blocks, the alignment results in an anisotropic refractive index of the solution parallel and perpendicular to the magnetic field. We present a model for calculating the magnetic birefringence, using solely the magnetic susceptibilities and optical polarizabil...
The addition of multifunctional additives comprised of singleor double-ring aromatic cores decorated at their periphery with multiple hydrogen-bond-donating groups such as carboxylic acid and phenol is shown to induce microphase segregation of otherwise disordered Pluronic BCP (poly(ethylene oxide-propylene oxide-ethylene oxide)) surfactant melts, resulting in the formation of well-ordered supr...
Back Cover: Supramolecular adhesive hydrogels based on α-cyclodextrin (αCD) capped decyl group-modified Alaska pollock gelatin and poly(ethylene) glycol-based crosslinker are designed. The resulting hydrogel can close the cerebral dura mater has excellent anti-swelling properties. These properties attributed to release of αCD from after curing subsequent assembly groups. This is reported by Tet...
Addition reaction of mesomorphic malonate-based dendrimers (up to the fourth generation) with C60 gave liquid-crystalline fullerene derivatives. The cyanobiphenyl unit was used as liquid-crystalline promoter. The malonates presented nematic and/or smectic A phases. The fullerenes showed only smectic A phases, with the exception of the second generation dendrimer for which smectic A and nematic ...
