Abstract
AbstractTransparent wood (TW) combining unique anisotropic structure has broad application prospects in the field of advanced building furniture materials. Many efforts have been made to add quantum dots or nanoparticles to TW to endow it with additional functionality, such as luminescent, electrochromic, and thermochromic TW. However, luminous TW with shape‐editable functionality and its new applications have yet to be explored. Benefiting from the excellent luminescence performance in a diluted solution state, BODIPY (4,4‐difluoro‐4‐bora‐3a,4a‐diazas‐indacene) dyes have been widely used for bio‐sensing and bioimaging. In addition, vitrimers exhibit excellent stimuli‐responsive, shape‐memory, and reprocessing properties thanks to exchangeable dynamic covalent crosslinking networks, which are suitable for fabricating smart TW. Herein, combing these advantages, a dual‐functional transparent wood composite (P‐SEFTW) with photoluminescent and shape editable function was developed by introducing BODIPY dyes and vitrimers into the delignified wood (DW) templates. P‐SEFTW displays good UV luminescence, unique light guiding and directional scattering effects. Meanwhile, it shows excellent shape‐recovery, shape‐programming, shape‐erasing, and re‐programming capability under thermal‐stimulus. These characteristics enable TW to exhibit great prospect as an advanced smart and functional building material.
