| Özet |
| Cyclic phosphazenes with positively charged substituents were investigated as surface modifiers for lanthanide phosphate nanoparticles. Cyclotriphosphazenes bearing aromatic (1, 2) and aliphatic (3-6) substituents with terminal tertiary amino functions have been synthesized and subsequently quaternized by treatment with methyl iodide. In subsequent tests, their influence as surface modifiers for the lanthanide phosphate-based nanoparticles was analysed with respect to the resulting particle solubility and the degree of surface interaction. While an interaction of the completely quaternized cyclic phosphazenes 2 and 4 with the nanoparticles leads to an agglomeration, stable nanocrystal-linker complexes in methanol could be formed with the compounds 5 and 6. Aromatic functions were not suitable due to interference with the UV absorbance of the nanocrystals, while aliphatic side chains allowed a good fluorescence detection of the nanocrystals with UV excitation without any loss of intensity as compared to the untreated particles. © 2008 Wiley-VCH Verlag GmbH & Co.
