Patent abstract
The present invention relates to a photochromic fluorescent polymer and a preparation method thereof, and more particularly, to a photochromic fluorescent polymer having bonds between diarylethenes and aryethene-vinylene precursors with a weight average molecular weight of 500 to 1,000,000, which exhibits highly improved photochromic and fluorescent characteristics compared to conventional photochromic fluorescent materials and excellent solubility to organic solvents, thus being applicable for photofunctional materials and information processing device such as optical recording, optical switches, non-destructive optical recording materials.
