Abstract
Official abstract text for this publication.
The present disclosure provides organic compounds having pseudocapacitive performance and methods of preparing said compounds. The organic compounds can include perylene diamine (PDI) subunits and hexaazatrinaphthylene (HATN) subunits.
First claim
Opening claim text (preview).
What is claimed is: 1 . A compound comprising: hexaazatrinaphthalene subunits; and perylene diimide subunits. 2 . The compound of claim 1 , wherein at least a portion of the hexaazatrinaphthalene subunits are covalently coupled to one or more of the perylene diimide subunits. 3 . The compound of claim 1 , wherein at least a portion of the hexaazatrinaphthalene subunits are covalently coupled to three of the perylene diimide subunits. 4 . The compound of claim 1 , wherein the compound is a polymer. 5 . The compound of claim 4 , wherein the polymer comprises subunits having a structure as shown in Formula I: wherein A represents the perylene diimide subunits and B represents the hexaazatrinaphthalene subunits. 6 . The compound of claim 4 , wherein the polymer is non-planar. 7 . The compound of claim 4 , wherein the polymer has a capacitance value of about 689 F/g at a current density of about 0.5 A/g. 8 . The compound of claim 4 , wherein the polymer has a yielding capacitance values of over about 430 F/g at a current density of about 75 A/g. 9 . A method of forming a polymer, comprising: i) copolymerizing hexaazatrinaphthalene building blocks with perylene diimide building blocks to form a first intermediate; ii) irradiating the first intermediate to form a second intermediate; and iii) thermolyzing the second intermediate to form the polymer. 10 . The method of claim 9 , wherein the copolymerizing comprises Suzuki cross-coupling. 11 . The method of claim 9 , wherein the hexaazatrinaphthalene building blocks comprise hexaazatrinaphthalene tris-boronic acid pinacol ester. 12 . The method of claim 9 , wherein the perylene diimide building blocks comprise 1,6- and 1,7-dibromoperylene-3,4,9,10-tetracarboxylicdiimide. 13 . The method of claim 12 , wherein 1,6- and 1,7-dibromoperylene-3,4,9,10-tetracarboxylicdiimide is further derivatized with alkyl chains. 14 . The method of claim 9 , wherein irradiating is performed with light having a wavelength in visible spectrum.
