a Band structures. The coordinates of high-symmetry points are Γ—C|C2—Y2—Γ—M2—D|D2—A—Γ|L2—Γ—V2 (orange lines). b HOMO at VB. c LUMO at CB. d Changes in the optical spectrum of EC-COF-1 film as a function of applied potential. e Repetitive display of transmittance at 574 nm (blue line) for the voltage between –1.8 and +2.0 V.
