This study examines temperature-induced transitions in both structural dimensionality and chirality of methylbenzylamine-based lead iodide perovskite thin films. The results demonstrate that thermal treatment enables pronounced wavelength tunability in circularly polarized light (CPL) recognition, which is closely correlated with a crystallographic transformation from a two-dimensional to a one-dimensional structure. Furthermore, the chiral optical response is successfully transduced into a measurable electrical signal in the form of photocurrent. These findings indicate that multi-wavelength CPL detection can be achieved using a single material system through simple thermal processing, offering a promising strategy for the development of next-generation CPL detection technologies.
