Redox-State Dependent Spectral Properties of Porous Organic Polymers containing Furan, Thiophene and Selenophene
A series of electroactive triarylamine porous organic polymers (POPs) with furan, thiophene and selenophene (POP-O, POP-S and POP-Se) linkers have been synthesised and their electronic and spectral properties investigated as a function of redox state. Solid state NMR provided insight into the structural features of the POPs, whilst in situ solid state Vis-NIR and EPR spectroelectrochemistry showed that the distinct redox states in POP-S could be reversibly accessed. The development of redox-active porous organic polymers with heterocyclic linkers affords their potential application as stimuli responsive materials in gas storage, catalysis and as electrochromic materials.
