Paper Title:
Synthesis and Mesophse Study on a Triphenylene-Based Polysiloxane
  Abstract

A side chain triphenylene-based polysiloxane were synthesized from 2-hydroxy-3-Methoxy-6,7,10,11–tetrapentyloxy-triphenylene.2-hydroxy-3-Methoxy-6,7,10,11–tetrapentyloxy triphenylene was synthesized via the common synthisis route including the Williamson Etherification of catechol, the iodination of 1,2-dipentyloxybenzene, the Ullman Coupling and the coupling of 3,3'-4,4'–tetrapentyloxy diphenyl and methoxy-phenol; 2-allyloxyl-3-Methoxy-6, 7, 10, 11–tetrapentyloxytriphenylene was synthesized by the etherification of 2-hydroxy-3-Methoxy-6,7,10, 11–tetrapentyloxytriphenylene and allyl bromide; the polysiloxane was synthesized by addition of 2-allyloxyl-3-Methoxy-6,7,10,11–tetrapentyloxytriphenylene and polydimethylsiloxane. The structures of the compounds were determined by FTIR and 1HNMR. Mesophase and their structural orders were determined using a polarized optical microscope and a differential scanning calorimeter.
