## Description

- description: Porphyrin is one of the most promising materials for realizing a practical
    artificial olfactory sensor system. In this study, we focus on non-substituted
    porphyrins—porphines—as receptor materials of nanomechanical membrane-type surface
    stress sensors (MSS) to investigate the effect of center metals on gas sensing.
    By omitting the substituents on the tetrapyrrole macrocycle of porphyrin, the
    peripheral interference by substituents can be avoided. Zinc, nickel, and iron
    were chosen for the center metals as these metalloporphines show different properties
    compared to free-base porphine. The present study revealed that iron insertion
    enhanced sensitivity to various gases, while zinc and nickel insertion led to
    equivalent or less sensitivity than free-base porphine. Based on the experimental
    results, we discuss the role of center metals for gas uptake from the view point
    of molecular interaction. We also report the high robustness of the iron porphine
    to humidity, showing the high feasibility of porphine-based nanomechanical sensor
    devices for practical applications in ambient conditions.
