Abstract Endowing the widely-used synthetic polymer nylon with high-performance organic room-temperature phosphorescence would produce advanced materials a great potential for applications in daily life and industry. One key to achieving this goal is find suitable luminophore that can access triplet excited state aid of matrix by controlling matrix-luminophore interaction. Herein we report highly-efficient nylons doping cyano-substituted benzimidazole derivatives into 6 matrix. These homogeneously doped show ultralong lifetimes up 1.5 s high quantum efficiency 48.3% at same time. The synergistic effect homogeneous dopant distribution via hydrogen bonding interaction, rigid environment polymer, energy transfer between luminophores important phosphorescence, as supported combined experimental theoretical results control compounds various polymeric matrices. One-dimensional optical fibers are prepared from these transport both blue fluorescent green afterglow photonic signals across millimeter distance without significant attenuation. phosphorescent dual information encryption rewritable recording illustrated.

Materials having room-temperature phosphorescence (RTP) are in limelight due to their advantageous long luminescence lifespan for applications optoelectronics, bioimaging, and security purpose devices. Development of metal- halogen-free organics persistent RTP has been envisaged through aggregation, heavy atom substitution, host–guest interactions, etc. In this article, we present experimental evidence the effect H-bonding other nonbonding interactions on types emission five carbazole derivatives. An unsubstituted showed only fluorescence powder form, while N-aryl-substituted carbonyl nitrile groups (Benzal-CN-Cbz, Acph-CN-Cbz, Bnph-CN-Cbz) dual consisting form under ambient conditions. Acph-CN-Cbz longest excited-state lifetime exceeding 1.2 ms form. Benzal-CN-Cbz, Bnph-CN-Cbz is correlated evident from single-crystal analysis. involving group extensive π–π caused close packing solid state associated with long-lived triplet excited RTP. Further, a up 1.5 s at temperature air was displayed drop-casted PVA films. To best our knowledge, few organics, without halogen atoms, available such lifetimes.
