Abstract The pursuit of sustainable, high‐performance organic ultralong room temperature phosphorescence (OURTP) materials with stimulus‐responsive properties presents a significant and enticing yet formidable challenge. Herein, an efficient strategy to confining boric acid‐based compounds into biomass macrocycle γ‐cyclodextrin through multiple interactions is developed, enabling the construction multicolor OURTP doped systems. synergistic effects strong hydrogen bonding, C─O─B covalent cross‐linking, host–guest encapsulation significantly suppress non‐radiative transition, culminating in extraordinary lifetime excellent quantum yield 4.65 s 32.8%, respectively, which are far superior reported RTP materials. Additionally, merging phosphors contributes stimulus responses, overcoming inherent limitations degradation recycling compounds, dynamically modulating signals multiple‐stimulus achieving integration multifunctional dynamic data processing techniques.

Abstract Stimulus‐responsive organic room temperature phosphorescent (RTP) materials have received significant attention in bioimaging, sensing, and data storage because of their controllable dynamic variability rapid response. Organic co‐crystals, with tailor‐designed optical properties through manipulation aggregate structures, proven to be very effective elucidating the structure‐property relationship RTP at molecular level. Therefore, enhancing rigid frameworks that promote intersystem crossing is a valid approach. Notably, realization co‐crystal performance by altering components or adjusting crystal lattices highly appealing; however, this has not been fully addressed. In study, an co‐crystal, 4,4′‐bipyridine (44BD), was employed as host, 1,4‐diiodotetrafluorobenzene (DITF) 4‐bromo‐2,3,5,6‐tetrafluorobenzoic acid (TFBA) were guests. The 44BD‐DITF exhibited orange RTP, whereas 44BD‐TFBA displayed bright yellow RTP. Crystal analysis theoretical calculations revealed dense packing abundant intermolecular interactions within these co‐crystals are crucial for emergence both show reversible acid/base stimulus response, is, exposure hydrochloric (HCl) fumes results quenching which can subsequently restored triethylamine (TEA) fumigation. This study presents approach towards switching thus offering opportunities development stimulus‐responsive next‐generation applications.

Developing nonconjugated materials with large Stokes shifts is highly desired. In this work, three kinds of hyperbranched aggregation-induced emission (AIE) polymers tunable n/π electronic effects were synthesized. HBPSi-CBD contains alkenyl groups in the backbone and possesses a promoted n−π* transition red-shifted wavelength shift 186 nm. Experiments theoretical simulations confirmed that planar π electrons are responsible for due to strong through-space n···π interactions restricted motions. Additionally, designed could be utilized as an ROS scavenger after coupling l-methionine. The HBPSi-Met exhibits remarkable scavenging properties capacity 77%. This work not only gains further insight into structure–property relationship AIE but also provides promising ROS-scavenging biomaterial treatment ROS-related diseases.

Activating delayed fluorescence emission in a dilute solution via non-covalent approach is formidable challenge. In this report, we propose strategy for efficient generation using supramolecularly engineered cyclophane-based nanoenvironments that provide sufficient binding strength to π-conjugated guests and can stabilize triplet excitons by reducing vibrational dissipation lowering the singlet-triplet energy gap emission. Toward goal, novel biphenyl bisimide-derived cyclophane introduced as an electron-deficient triplet-generating host. Upon encapsulation of various carbazole-derived inside nanocavity cyclophane, emissive charge transfer (CT) states close level bisimide are generated.
