(a) Conductivity transient using flash photolysis time-resolved microwave conductivity methods on excitation with a 355-nm laser pulse. (b) Time-of-flight transient current integration for CS-COF with a 355-nm laser pulse at a power of 34 mJ cm–2 per pulse. (c) Schematic representation of synthesis of CS-COF⊃C60 by sublimed crystallization of fullerenes in the open one-dimensional channels (white: carbon; red: nitrogen; purple: fullerene). A side view of CS-COF⊃C60 is also shown. (d) I–V curve of a 50-nm-thick CS-COF⊃C60/PMMA film sandwiched between Al and Au electrodes at bias voltages ranging from –1.5 to 1.5 V in air at 25 °C. (e) Photocurrent switching at a bias voltage of 1.5 V in air at 25 °C, with repetitive light on-off actions on the 50-nm-thick CS-COF⊃C60/PMMA film. (f) J–V curve of the photovoltaic cell under irradiation with air mass 1.5 conditions (VOC=0.98 V, JSC=1.7 mA cm–2, FF=0.54).
