Abstract:
A C3-symmetric benzotrithiophene tricarbaldehyde (BTT) is synthesized for the first time with a facile method, which is used to construct BTT-based covalent organic frameworks (COFs) with different pore sizes. Meanwhile, the structure transformations of the COFs under high-temperature ionothermal condition are studied systematically, and the relationships between the regularly changed structures of the further-cross-linked COFs and their supercapacitor performances are investigated. It turns out that dealing with COFs of designated structures under ionothermal condition is a great method to build highly conductive structure-controllable materials for electrochemical applications.

Covalent Bonds
When two atoms share electrons to complete their valence shells, they create a covalent bond. An atom's electronegativity—the force with which shared electrons are pulled towards an atom—determines how the electrons are shared. Molecules formed with covalent bonds can be either polar or nonpolar. Atoms with similar electronegativities form nonpolar covalent bonds; the electrons are shared equally. Atoms with different electronegativities share electrons unequally,...
