Among the stimuli-responsive materials, thermochromic materials have received tremendous scientific attention. However, traditional organic or inorganic thermochromic materials need a complex preparation process and possess a single performance. Herein, we report a new 1D organic−inorganic hybrid material, lead iodide hybrid, [PbI 4 •4-MAPY] (CP-1) (4-MAPY = pyridin-4-ylmethanamine), with line-sharing PbI 6 octahedral chains and excellent reversible thermochromic properties (transition between lemon yellow and carmine red). In addition, the results of experimental and theoretical calculations illustrate that [PbI 4 •4-MAPY] is an indirect band gap semiconductor, and the band structures are contributed by inorganic chains. Overall, this work might afford a strategy for the detection of new dielectric and thermochromic switchable materials.
