Description
Summary:•1D metallosupramolecular polymer constructed by diazananographene and porphyrin cobalt(II).•Solution-soluble metallosupramolecular polymer•Energy transfer from porphyrin units to diazananographene units. A one-dimensional (1D) metallosupramolecular polymer, consisting of diazananographene (C76N2) and porphyrin cobalt(II) (CoTPP), was synthesized through coordination between pyridinic nitrogen and cobalt (II). Its structure was unambiguously characterized by single crystal X-ray diffraction. Revealed by NMR spectroscopy, this complex in solution still adopted a polymeric structure. The steady and transient absorption spectroscopic measurements of metallosupramolecular polymer indicated fast vibrational relaxation of CoTPP and energy transfer from CoTPP to C76N2.
