      abstract     = {Tetraaza[14]annulenes (TAA) are synthetic macrocycles which
                      are analogue to porphyrins. However, there are almost no
                      reports about the synthesis of polymers based on TAA and
                      neither on their use as electrocatalysts. The study of new
                      catalysts to promote an efficient electrochemical conversion
                      of carbon dioxide to valuable chemicals is a promising
                      approach to relieve the pressure of carbon emissions and
                      realize the carbon cycle. Herein, we first report the
                      synthesis of a novel tetraaza[14]annulene (TAA) based
                      organic polymeric metal complex (PMC) by a non-template
                      method. This PMC is used as ligand to construct a π-d
                      conjugated cobalt coordination polymer (Poly-TAA-Co) with
                      CoN4 structure which is supported on multi-wall carbon
                      nanotubes (CNTs) to work as an atomically dispersed
                      efficient electrocatalyst for the CO2 reduction reaction
                      (CO2RR). The resulting catalyst (Poly-TAA-Co-CNT) exhibits
                      excellent performance, with a $90\%$ CO faradaic efficiency,
                      a low overpotential (390 mV) and good stability in 0.5 M
                      KHCO3 aqueous solution. Density functional theory
                      calculations confirmed that the cobalt tetra[14]annulene is
                      an excellent active site for electrocatalytic CO2RR. This
                      work not only inspires the design of novel TAA based
                      macromolecules, but also paves the way to the development
                      and application of new molecular-based catalysts for
                      electrocatalytic CO2RR.},
