Abstract :
We have developed a highly sensitive, transparent and flexible toluene sensor using cobalt-metalloporphyrin (Co-MPP)-functionalized graphene as sensing material. The functionalization of MPP enhanced responsiveness (ΔR/Ri) over 200% compared to pristine graphene toward 10 ppm of toluene molecules at room temperature, while it still revealed optical transmittance and mechanical flexibility.
