Fig. 7. The variation of the PDOS of (A) Py-COF (upper panel: Py units and lower panel: imine units), (B) Tet-COF (upper panel: Tet units and lower panel: Imine units), and (C) Tpe-COF (upper panel: Tpe units and lower panel: imine units) before and after photoexcitation. Real-space hole (blue regions) and electron (green regions) distributions of (D) upper panel: Py-COF and lower panel: Py-hCOF, (E) upper panel: Tet-COF and lower panel: Py-hCOF, and (F) upper panel: Tpe-COF and lower panel: Tpe-hCOF.
