Synthesis and Mesogenic Properties of a Novel Hyperbranched Triphenylene-Based Discotic Liquid Crystal
A novel triphenylene-based hyper-branched macromolecule was synthesized from the functional compound-2, 6, 10-trihydroxy-3, 7, 11–tris (pentyloxy) triphenylene serving as core, using α,ω-dibromodecane as spacer and 1-bromopentane as terminal group for end capping by using a very simple synthesis method, one-pot reaction. The structure of the hyperbranched macromolecule was determined by FTIR and 1HNMR. The molecule weight and the molecular weight distribution were measured by GPC. Mesophase and their structural orders were determined using a polarized optical microscope and a differential scanning calorimeter.
