Dithienothiophene (DTT) based conjugated microporous polymers (CMPs) were synthesized by bulk and electrochemical oxidative polymerizations. Spectroelectrochemical measurements showed that DTT-CMP can be reversibly oxidized and reduced, accompanied by a significant change of the absorption properties making the material interesting for electrochromic devices. Reversible doping and dedoping of the bulk polymer network was also observed using iodine and ammonia, respectively. Nitrogen gas sorption measurements of the neutral, doped, and dedoped polymer networks indicated the presence of iodide species within the pores, and the conductivity of the networks is highly increased upon doping with iodine. The introduction of the strong electron donor DTT into a conjugated porous network, and the ability for redox switching, make DTT-CMPs interesting materials for organo(opto)electronic devices and sensors. Synthesis and (electro)chemical redox properties of a dithienothiophene (DTT) based conjugated microporous polymer have been investigated. The network exhibits high permanent surface areas of 790m2g-1 and can be reversibly oxidized and reduced, either chemically or electrochemically, accompanied by a significant color change.
