Recent Advancements of Hexaazatriphenylene-Based Materials for Energy Applications

Hexaazatriphenylene (HAT) is an electron deficient, rigid, planar, aromatic discotic molecule with three fused pyrazine rings and excellent π-π stacking ability.Due to its excellent topology and electronic properties, HAT has been exploited as structural motifs of supramolecules, covalent organic frameworks (COFs), porous hydrogen-bonded organic frameworks (HOFs), and metal organic frameworks (MOFs).HAT derivatives have been utilized in catalysis, semiconductors, monomolecular magnets, water oxidation, proton conduction, etc.In recent years, motivated by the increasing energy demand, scientists have intensively studied the energy applications of HAT derivatives.In this paper, the recent progress of HAT derivatives in the field of energy has been reviewed.
