Abstract

Full substituted p-(dodecyloxy)-phenol derivative of cyclotriphosphazene (trimer) was synthesized in orderto investigate its mesogenic properties. Firstly, p-(dodecyloxy)-phenol (1) was synthesized from the reactionof hydroquinone and 1-bromododecane. Hexachlorocyclotriphosphazene (trimer) was reacted in a 1:8molar ratio in tetrahydrofurane (THF) presence of sodium hyride (NaH) as base at room temperature for 24hours and then under the reflux for a day. Full substituted derivative (2) was obtained and its structure wasdetermined by mass analysis, and by FT–IR, 1H and 31P {1H} NMR spectroscopic techniques. Additionallythermal and mesomorphic behaviours were examined by differential scanning calorimetry (DSC),polarising optical microscopy (POM) and X-ray diffraction (XRD) techniques. By contrast with literature,results showed that compound 2 has liquid crystal behavior.
