Firstly, p-(dodecyloxy)-phenol (1) was synthesized from the reaction </font> </p> <p> <font color="#337ab7">of hydroquinone and 1-bromododecane. Hexachlorocyclotriphosphazene (trimer) was reacted in a 1:8 </font> </p> <p> <font color="#337ab7">molar ratio in tetrahydrofurane (THF) presence of sodium hyride (NaH) as base at room temperature for 24 </font> </p> <p> <font color="#337ab7">hours and then under the reflux for a day. Full substituted derivative (2) was obtained and its structure was </font> </p> <p> <font color="#337ab7">determined by mass analysis, and by FT–IR, 1H and 31P {1H} NMR spectroscopic techniques. Additionally </font> </p> <p> <font color="#337ab7">thermal and mesomorphic behaviours were examined by differential scanning calorimetry (DSC), </font> </p> <p> <font color="#337ab7">polarising optical microscopy (POM) and X-ray diffraction (XRD) techniques. By contrast with literature, </font> </p> <p> <font color="#337ab7">results showed that compound 2 has liquid crystal behavior. </font> </p> <p> <br /> </p>}, number={3}, publisher={Manisa Celal Bayar Üniversitesi}
