Chiroptical materials have received much attention in diverse fields for applications such as displays, sensors, smart memory devices, and catalysis. Here, we develop a simple fabrication method for polymer films with tunable chiroptical properties using small amounts of self‐assembling fluorescent dye as an additive. Both the circular dichroism and circularly polarized luminescence signals of the film can be tuned between positive and negative values by thermal treatment. The chiroptical properties can be varied by slight changes in the orientation of chiral pyrene moieties in self‐assembled nanofibril networks.
