Özet
Full substituted dodecyloxy derivative ofcyclotetraphosphazene was synthesized in order to investigate its mesomorphicproperties. Octachlorocyclotetraphosphazene (tetramer) was reacted withdodecanol in tetrahydrofuran (THF) presence of sodium hydride (NaH) as base atroom temperature for 24 hours and then under the reflux for a day. Fullsubstituted derivative (1) wasobtained and its structure was determined by mass analysis, and by FT–IR, 1Hand 31P {1H} NMR spectroscopic techniques. Additionally,thermal and mesomorphic behaviours were examined by differential scanningcalorimetry (DSC), polarizing optical microscopy (POM) and X-ray diffraction(XRD) techniques. Obtained results showed that compound 1 has liquid crystal behaviour.
