Photodynamic behavior controlled by the synergy of electron transfer and charge transfer has been characterized in two regioisomeric pyridinium‐bearing coordination polymers ( Cd‐Bip and Cd‐Bpy ) with the help of a smart charge‐distribution‐related isoreticular strategy. Because it is relatively weak, the charge‐transfer interaction between adjacent 2D networks in Cd‐Bip can be easily perturbed by photoinduced electron transfer under irradiation with 365 nm light, and then successfully drives the occurrence of photodynamic behavior. In contrast, lower energy 450 nm light is absorbed to a lesser extent, and can only induce a low degree of electron transfer, which is insufficient to actuate operation of this photodynamic behavior in Cd‐Bip .
