For bulk polymers, the EBE is larger than k B T (~ 25 meV), so excitons cannot dissociate at room temperature. Therefore, the supply of an additional energy is required to overcome the EBE. Since exciton dissociation can be impelled on the polymer-solution interface or polymer-polymer interface in heterogeneous materials , 2D polymers that have high surface area of polymer-water interface are appealing candidates to achieve high quantum efficiencies . Computational investigations indicate that the EBE of graphitic carbon nitrides can be reduced by increasing the polymerization of the structures, thereby helping to improve the exciton dissociation efficiency .
