Summary: In recent years, the challenge of achieving a high quantum yield (QY) in dilute solutions of non-aromatic fluorescent materials has received widespread attention. This study successfully designed a bioinspired molecule with a dipeptide-like structure and active silanol groups, inspired by the Clustering-triggered emission (CTE) phenomenon. The hydrolysate hPDs obtained by simple heating of the bioinspired molecule can emit strong blue fluorescence in dilute solution, and this is the first time that the emission behavior of non-aromatic fluorescent materials has been realized under sunlight. The high QY of h-PDs in aqueous solution and solid state, attributed to the condensation of active silanol groups and the presence of hydrogen bonds and N-Si coordination bonds, allows small molecules to cross-link and aggregate into dense clusters.

Summary: In this paper, a new biomass adhesive is proposed to replace the widely used tri-formaldehyde glue, which is harmful to human health. The new adhesive is a hyperbranched polyester prepared from glycerol and maleic anhydride using a solvent-free method. It has better bonding and water resistance properties compared to tri-formaldehyde adhesive and can be replicated in industry due to its simple synthesis process.

Summary: This study demonstrates the facile synthesis of white light-emitting carbon quantum dots from corncob using a hydrothermal method, showing high photoluminescence intensity and stability over time. The presence of Si and N impurities in the biomass contributes to the high quantum yield and enhanced lifetime of the quantum dots. These carbon quantum dots exhibit high sensitivity towards various substances in fluorescence sensing, with potential applications in optical sensor development. Additionally, flexible white light-emitting sheets fabricated from the carbon quantum dots display uniform brightness, good color reproducibility, and increased stability under UV light excitation.
