Sustainable photoactivated room temperature phosphorescent materials exhibit great potential but are difficult to obtain. Here, we develop by covalently attaching lignin polylactic acid, where and acid the chromophore matrix, respectively. Initially phosphorescence of is quenched residual O2. However, switched on when oxygen consumed triplet excitons under continuous UV light irradiation. As such, lifetime increases from 3.0 ms 221.1 after 20 s activation. Interestingly, again being kept an atmosphere air for 2 h in absence irradiation due diffusion into materials. Using these properties, as-developed material successfully used as a smart anti-counterfeiting logo medicine bottle information recording. Convenient sustainable (RTP) wide ranging applications Here authors RTP acid.

Abstract Producing room temperature phosphorescent (RTP) materials from biomass resources using a solvent free method is essential but hard to achieve. Here, we discovered that lignin dissolved well in the liquid monomer, 2-hydroxyethyl acrylate (HEA), due extensive hydrogen bonding and non-bonding interactions between HEA. Motivated by this discovery, developed system consisting of HEA urethane dimethacrylate (UDMA) for converting into RTP materials. With design, generated radicals upon UV irradiation, which initiated polymerization (as monomer) UDMA crosslinker). The as-obtained polymer network rigidifies activates humidity/water-resistant with lifetime 202.9 ms. Moreover, afterglow color was successfully tuned red after loading RhB via energy transfer (TS-FRET). Using these properties, as-developed material used as photocured multiple-emission inks, luminescent coatings smart anti-counterfeiting logo medicine bottle.

Room temperature phosphorescent (RTP) hydrogels exhibit great potential but show poor mechanical performance (Tensile strengthen <1 MPa) and non-tunable RTP performance, hindering their practical applications. Here, we develop wood hydrogel (W-hydrogel) by the in situ polymerization of acrylamide presence delignified wood. As a result molecular interactions between components polyacrylamide, W-hydrogel tensile 38.4 MPa green emission with lifetime 32.5 ms. Moreover, strength are increased to 153.8 69.7 ms, upon treating ethanol. Significantly, is switched alternating "ethanol water" treatments. Additionally, used as energy donor order produce red afterglow using RhB via an transfer process. Taking advantage these properties, processed into multiple hydrogel-based luminescent materials.
