Herein, the synthesis and characterization of two robust tungsten rhenium carbonyl complexes integrated into an organic polymer ( CPP‐Re , CPP‐W ) are reported. These polymers obtained by a Suzuki coupling reaction between corresponding dibromo metal‐carbonyl substituted dipyrido[3,2‐a:2′,3′‐c]phenazine complex 1,3,5‐triphenylbenzene‐4′,4″,4″,4‴‐triboronic acid catalytic active sites photosensitizer since they have not only nitrogen to coordinate metal centers as or but photoactive units with good charge‐separating ability which can significantly improve CO 2 photoreduction (CO PRR). show similar activity in solid–gas PRR absence sacrificial agents produce syn gas + H CPP ‐W selectivity products change regarding being able also large amount more demanding electron such methane ethane. Moreover, single‐site Re‐ W‐CPP catalysts could prevent dimerization that produces its deactivation. This work shows potential CPPs matrices support single for heterogeneous catalysis.
