Dithiine-linked metalphthalocyanine framework with undulated layers for highly efficient and stable H₂O₂ electroproduction.

ABSTRACT: Realization of stable and industrial-level H₂O₂ electroproduction still faces great challenge due large partly to the easy decomposition of H₂O₂. Herein, a two-dimensional dithiine-linked phthalocyaninato cobalt (CoPc)-based covalent organic framework (COF), CoPc-S-COF, was afforded from the reaction of hexadecafluorophthalocyaninato cobalt (II) with 1,2,4,5-benzenetetrathiol. Introduction of the sulfur atoms with large atomic radius and two lone-pairs of electrons in the C-S-C linking unit leads to an undulated layered structure and an increased electron density of the Co center for CoPc-S-COF according to a series of experiments in combination with theoretical calculations. The former structural effect allows the exposition of more Co sites to
