Synthesis, Characterisation And Determination Of Mesophase Transition Of Cyclotriphosphazene Derivatives With Azo Linking Unit

A series of intermediates were synthesised via azo coupling reactions to give the alkylated compounds with one azo linking unit, 2a-c and with two azo linking units, 5a-c. These intermediates were subjected to further monosubstitution and hexasubstitution reactions with cyclotriphosphazene to produc...
