A novel “wheel-and-axle” architecture (c-P6)m/(FeBz)n, with (c-P6) denoting the wheel formed by six porphyrin-based segments and (FeBz)n the axle formed by the 1D iron benzene multidecker complex, is designed, and its electronic structure, transport property, and linear photoresponse are investigated. (c-P6)m/(FeBz)n shows a spin-polarized transport property. The spin filter efficiency of (c-P6)m/(FeBz)n can be > 90%, suggesting it is a very good candidate for spin filters. Furthermore, a distinct NDR feature is observed for (c-P6)m/(FeBz)n so it is can be used for making electronic switches and oscillators. Under linear light, both the wheel and axle of (c-P6)m/(FeBz)n exhibit a distinct polarized photoresponse character. The magnitude of the photoresponse can be tuned by the photon energy or by the l bias voltage. An off–on–off switch is observed within the considered photon energy range, showing potential application for optical switches. All these fascinating properties of (c-P6)m/(FeBz)n make the new 1D material especially attractive for electronic and optoelectronic devices.
