Structural and thermosensitive properties of novel octopus shape cyclotriphosphazenes

Abstract

Three novel compounds (3-5) were synthesized from the reactions of non-geminal cis-2,4,6 diethylene glycol monobutyl ether substituted cyclotriphosphazene (2a) with ethylamine, hexylamine and dodecylamine. Compounds 3-5 were characterized by P-31 NMR, MS and elemental analysis. The thermosensitive properties of compounds 3-5 were investigated. Compound 3 showed thermosensitive properties which might enable it to be used as a biomedical material. (C) 2010 Elsevier Ltd. All rights reserved.
