Thermochromic fluorescent materials (TFMs) have attracted significant attention due to their unique colorimetric response temperature. However, existing TFMs still suffer from weak stimulus responsiveness, broad temperature ranges, uncontrollable emission color changes, and low quantum yields. In this study, we address these issues by designing synthesizing three diketone-boron complexes with distinct wavelengths (NWPU-(2-4)). Utilizing a molecular engineering strategy manipulate intramolecular charge transfer transitions packing modes, our synthesized exhibit efficient fluorescence in both solution solid states. Moreover, are highly sensitive environmental polarity. By incorporating compounds into thermosensitive matrices of long-chain alkanes, produced varied peak variation ranges. Notably, the TFM based on NWPU-4, owing its strong dense J-aggregate configuration, not only exhibits intense spanning deep red near-infrared spectrum but also displays remarkable 90 nm range thermochromic properties. Ultimately, it was successfully applied programmable, thermally controlled, multi-level information encryption.
