Synthesis and characterization of polyphosphazene with coumarin as side group
关键字:coumarin
Since the proneering works on soluble polyphosphazene done by Allcock, this kind of inorganic polymer have been attracted more and more attention from 1960s. Its chemical, irradiative and oxidative stability makes it find many app...

[Polymers] Coumarin- and Carboxyl-Functionalized Supramolecular Polybenzoxazines Form Miscible Blends with Polyvinylpyrrolidone
In this study, we synthesized a novel multifunctional benzoxazine monomer (Coumarin-COOH BZ), possessing both coumarin and COOH groups, through the reaction of 4-methyl-7-hydroxycoumarin, 4-aminobenzoic acid, and paraformaldehyde in 1,4-dioxane, with the structure confirmed using 1H and 13C nuclear magnetic resonance and Fourier transform infrared (FTIR) spectroscopy. Differential scanning calor...

Photo-Dimerization Characteristics of Coumarin Pendants within Amphiphilic Random Copolymer Micelles
The photo-dimerization characteristics of coumarin pendants within amphiphilic random copolymer micelles in aqueous solution was comprehensively investigated using various selected wavelength light in the UV-Vis-NIR region. The time-dependent photo-dimerization degree (PD) changes in the photo-dimerization experiments showed saturating behaviors with intensity-independent of PDmax value...

Fabrication of Novel Coumarin Derivative Functionalized Polypseudorotaxane Micelles for Drug Delivery
The fabrication and drug delivery of novel polypseudorotaxane micelles with small molecule coumarin derivative as hydrophobic segment were reported. 7-Carboxymethoxy coumarin was immobilized on the terminal hydroxyl groups of poly(ethylene glycol) (PEG). The modified PEG chains were threaded in a-cyclodextrins (a-CDs) to form polypseudorotaxanes. The polypseudorotaxanes self-assembled into supramo...

Photo-induced dynamic association of coumarin pendants within amphiphilic random copolymer micelles
关键字:Photo-induced,amphiphilic random copolymer micelles
The water-soluble amphiphilic random copolymer of P(DMA-co-VBC) with coumarin pendants has been designed to investigate the photo-induced dynamic association of coumarin pendants within polymer micelles in aqueous solution. Methods of absorption and emission spectra, solution transmittance, dynamic light scattering (DLS), and atomic force microscope (AFM) were applied. It was f...
