Organic room-temperature phosphorescence (RTP) emitters with long lifetimes, high exciton utilizations, and tunable emission properties show promising applications in organic light-emitting diodes (OLEDs) biomedical fields. Their excited-state are highly related to single molecular structure, aggregation morphology, external stimulus (such as hydrostatic pressure effect). To gain a deeper understanding effectively regulate the key factors of luminescent efficiency lifetime for RTP emitters, we employ thermal vibration correlation function (TVCF) theory coupled quantum mechanics/molecular mechanics (QM/MM) calculations investigate photophysical three reported crystals (Bp-OEt, Xan-OEt, Xan-OMe) elastic/plastic deformation. By analyzing geometric structures stacking modes these crystals, observe that structure variations influence electronic structures, subsequently modifying transition energy consumption processes. Specifically, presence strong π–π interactions hydrogen bonds Xan-OEt crystal inhibits nonradiative decay process, thereby realizing long-lived emission. Additionally, hybridized local charge-transfer (HLCT) feature largest charge transfer excitation contributions (57.74%) stabilizes triplet excitons facilitates radiative ultimately achieving emissions. Furthermore, by applying Bp-OEt crystal, efficiencies lifetimes enhanced blue-shifted. All results demonstrate crucial role well effect regulating properties. Thus, our findings reveal structure-packing-property relationship highlight control packing approaches, which could provide prospective strategies constructing stimuli-responsive practical applications.

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.
