Donor-acceptor (D-A) alignment that integrates D-A pairs into the modular and versatile crystalline metal-organic frameworks is a powerful strategy to precisely fabricate multifunctional materials with unique optoelectronic properties and applications at the molecular level. Herein, we reported an unprecedented threefold interpenetrating D-A hybrid framework by incorporating an electron-deficient linear viologen zwitterion into the lead-halide systems. The 1D iodoplumbate nanoribbon and interpenetrating close-packed D-A structure endowed this hitherto unknown semiconductive alignment with the anisotropic conductivity and high stability. When used in a thermal sensor, it presented exceptional electrical properties with a high sensitivity (high thermal index of 4671 K) and decent temperature coefficient of resistivity (0.72% °C) in wide operational temperature ranges (40-220 °C), which are among the best of the related thermistors. This work develops a pathway to bridge the gaps between hybrid materials and electron devices.
