Triphenylene-based side chain DLCPs have been frequently investigated,concerning the MW effect,the spacer lengths influence and the hierarchical superstructure organization,While the underdeveloped research situation in TP-based main chain DLCPs is mainly in respect that relatively arduous synthesis of difunctional triphenylene derivatives,especially those with dihydroxy groups which are converted easily to ethers or esters,as the precursor molecules for the preparation of main chain polymers.
