The role of furyl substituents of pyrene on monomer and polymer properties

• The CV measurements presented high electrochemical stability of the obtained polymers.
• Furthermore, electrochemical studies of obtained compounds were described.
• UV–vis and fluorescence properties of obtained materials were reported.
• The batochromic shift was observed with increased number of furyl substituents.

This paper estimates the influence of substituents number on basic electrochemical, optical and electronic properties of monomers compared to their polymers. Results exhibit differences of these effects in monomers and polymers. The crosslinking effect has impact on basic properties of studied polymers. Polymers were created from their monomers by electropolymerization. Optical properties of a series of furyl derivatives of pyrene were investigated by UV–vis spectroscopy. Basic electrochemical properties of the studied compounds were investigated by cyclic voltammetry. ESR–UV–vis spectroelectrochemistry reveals differences in doping processes of obtained conjugated polymers. Good electrochemical stability of novel furyl-pyren π-conjugated polymers confirm the application potential of this group of materials for the development of organic semiconductors in particularly for possible applications in electrochromic devices, light emitting electrochemical cells and spintronic.
