1) Photochromic functional dye creation: new strategies and parent creation of photochromic dyes with visible light and long wavelength ( λ> 600 nm);
2) Expansion of new applications of photoregulated biology: photochromic dyes are used in super-resolution imaging probes and photocontrolled hydrogels as biomedical materials;
3) Exploration of organic/ionic thermoelectric materials: wearable thermoelectric materials based on functional dyes and ionic thermoelectric systems.
