“…The results of these measurements are exemplarily shown using the Zr 5 /PMMA particles. Light scattering was carried out in THF at 25 °C and data analysis was performed using an integral-type function to the correlation function by a constrained regularization method . Zr 5 /PMMA nanoparticles ( M w = 38 000; PDI = 1.46) showed a number-weighted diameter of 6.0 ± 0.4 nm.…”

Novel surface-functionalized metal oxo clusters were obtained using an in situ surface-modification method based on the sol−gel process. A reaction of 2-bromoisobutyric acid with Zr(OPr)4 or Ti(OiPr)4 resulted in the compounds Zr5O4(BrC(CH3)2COO)10(OnPr)2(nPrOH)4 and Ti6O4(BrC(CH3)2COO)8(OiPr)8. The reaction of 2-bromopropionic acid with VO(OiPr)3 resulted in the cluster V3O3(BrC(CH3)COO)6(HOiPr). All obtained compounds have in common that the organic functionalities are exclusively located on the surface of the well-defined sub-nanometer metal oxo clusters. The prepared compounds were successfully used as macroinitiators in atom transfer radical polymerizations (ATRP) and produced inorganic−organic core−shell nanoparticles.

Water‐soluble diblock copolymer, poly(N‐isopropylacrylamide)‐block‐poly(N‐vinyl‐2‐pyrroridone) (PNIPAMm‐b‐PNVPn), was found to associate with fullerene (C60), and thus C60 can be solubilized in water. The 63C60/PNIPAMm‐b‐PNVPn micelle formed a core‐shell micelle‐like aggregate comprising a C60/PNVP hydrophobic core and a thermoresponsive PNIPAM shell. The C60‐containing polymer micelle formation and its thermoresponsive behavior were characterized using light scattering and 1H NMR techniques. The hydrodynamic radius (Rh) of the C60‐bound polymer micelle increased with increasing temperature, which was ascribed to the hydrophobic association between dehydrated PNIPAM shells above lower critical solution temperature (LCST). 1H NMR data suggest that the motion of the PNIPAM block is restricted above LCST due to the dehydration of the PNIPAM shell in water. The generation of singlet oxygen by photosensitization by the C60‐bound polymer micelle was confirmed from photooxidation of 9,10‐anthracenedipropionic acid. Furthermore, DNA was found to be cleaved by visible light irradiation in the presence of the C60‐bound polymer micelle. Therefore, there may be a hope for a pharmaceutical application of the C60‐bound polymer micelle to cancer photodynamic therapy. © 2011 Wiley Periodicals, Inc. J Polym Sci Part A: Polym Chem, 2011.

Tetrafunctional porphyrins-containing trithiocarbonate groups were synthesized by an ordinary esterification method. This tetrafunctional porphyrin (TPP-CTA) could be used as a chain transfer agent in a controlled reversible addition-fragmentation chain transfer (RAFT) radical polymerization to prepare well-defined 4arm star-shaped polymers. N,N-Diethylacrylamide was polymerized using TPP-CTA in 1,4-dioxane. Poly(N,N-diethylacrylamide) (PDEA) is known to be a thermo-responsive polymer, and exhibits a lower critical solution temperature (LCST) in water. The star-shaped PDEA polymer (TPP-PDEA) was therefore also thermo-responsive, as expected. The LCST of this polymer depended on its concentration in water, as confirmed by turbidity, dynamic light scattering (DLS), static light scattering (SLS), and 1 H NMR measurements. The porphyrin cores were compartmentalized in PDEA shells in aqueous media. Below the LCST, the fluorescence intensity of TPP-PDEA was about six times larger than that of a water-soluble low molecular weight porphyrin compound (TSPP), whose fluorescence intensity was independent of temperature. Above the LCST, the fluorescence intensity of TPP-PDEA decreased, while the intensity was about three times higher than that of TSPP. These observations suggested that interpolymer aggregation occurred due to the hydrophobic interactions of the dehydrated PDEA arm chains above the LCST, with self-quenching of the porphyrin moieties arising from these interactions.
