摘要：

The synthesis and properties of naphthoxycyclotriphosphazenyl-substituted dendrimeric cyclic phosphazenes are reported. Compound 3, [N3P3(ONp)(5)OPhOH], is prepared by the sequential reactions of hexachlorocyclotriphosphazene with 2-naphthol and 4-benzyloxyphenol derivatives, as side groups. The dendrimeric compounds 5,6 and 7 have been obtained by the reactions of compound 3 with hexachlorocyclotriphosphazene, N3P3Cl6, octachlorocyclotetraphosphazene, N4P4Cl8, and bisphenol bridged cyclophosphazene, N6P6Cl10 (4), respectively. The newly synthesized compounds have been fully characterized by elemental analysis, ESI, MALDI-TOF mass spectrometry, FT-IR, H-1, C-13 and P-31 NMR spectroscopy. The thermal stability and fluorescence spectral properties of all these novel compounds are investiga ted. (C) 2012 Elsevier Ltd. All rights reserved.
