Furthermore, we anticipate that this time-resolved study will provide several clues to improve the photocatalytic efficiency of the molecular organic antenna like PyrBpy units within a porous polymer network by (i) the control of the flexibility and topology of the framework that clearly control the ratio and lifetime of the MICT and TICT states, by (ii) the optimization of the distribution of the metal catalyst based on the energy transfer efficiency, and by (iii) taking into account the interaction of the sacrificial electron donor present in high concentration in the porous polymer suspension. All these parameters are accessible by systematic time-resolved investigation of photoactive porous polymers, and in line with theoretical modeling, can drive the design of more efficient photocatalyst for the light-tochemical energy conversion.
