Abstract The development of high‐performance organic blue light‐emitting emitters is in urgent to act as an excitation source contribute the white light generation. On other hand, investigation on optical waveguides have been received increasing attentions because they can manipulate propagation accurately microscale boost optoelectronic and energy conversion applications. In this work, we facilely prepared a deep‐blue aggregation‐induced emission (AIE) dye, namely TPP‐4OMe, which shows high luminescent efficiency, narrow band good stability aggregate state. TPP‐4OMe be fabricated AIE microfibers readily with definite morphology composition. Based microfibers, active waveguide transmit signals achieved very low loss coefficient ( α ) 6.7 × 10 −3 dB μm −1 . Meanwhile, full‐visible broadband low‐loss passive well performed these has never observed pure crystals. More interestingly, excellent properties enable them wave‐guiding source, resulting distinct emission. present work not only provides materials but also bridges realize efficient accelerate practical

The π-bond enrichment frameworks not only serve as a crucial building block in organic synthesis but also assume pivotal role the fields of materials science, biomedicine, photochemistry, and other related disciplines owing to their distinctive structural characteristics. incorporation various substituents into C═C double bonds tetrasubstituted alkenes is currently highly significant research area. However, with diverse on poses challenge achieving stereoselectivity. Here, we reported an efficient convergent route Cu-catalyzed borylalkynylation both symmetrical unsymmetrical 1,3-diynes, B2pin2, acetylene bromide construction boronated phenyldiethynylethylene (BPDEE) derivatives excellent chemo-, stereo-, regioselectivities. BPDEE could transform novel π-conjugated gem-diphenyldiethynylethylene (DPDEE), vinylphenyldiethynylethylene (VPDEE), phenyltriethynylethylene (PTEE) by stepwise process, which provides flexible platform for complex that were difficult synthesize previous methods. initial optical characterization revealed synthesized molecules exhibited aggregation-induced emission (AIE) properties, further establishes groundwork future applications enriches advances field functional research.

Abstract Inkless and erasable printing (IEP) based on chromic materials holds great promise to alleviate environmental sustainable problems. Metal–organic polymers (MOPs) are bright platforms for constructing IEP materials. However, it is still challenging design target MOPs with excellent specific functions rationally due the intricate component‐structure‐property relationships. Herein, an effective strategy was proposed rational IEP‐MOP The stimuli‐responsive viologen moiety introduced into construction of give potential behaviors two different coordination models (i. e. bilateral model, M 1 ; unilateral coordinated 2 ) same ligand were designed. Aided by theoretical calculations, model recommended secondarily as a more suitable system Along this line, representative viologen‐Zn II synthesized successfully. Experiments exhibit that does have quicker stimuli response, stronger color contrast longer radical lifetime compared .

Mechanoscientific research fields encompassing chemistry, physics, and biology have advanced significantly over the last two decades. Notably, study of photon-emitting phenomena in molecular solids responsive to mechanical stimulation is known as mechanoresponsive luminescence (MRL) mechanoluminescence (ML). These exhibit significant potential for applications such sensor technology anti-counterfeiting measures. The versatility observed designs, enabling control thresholds wavelengths, coupled with diverse mechanisms inducing deformation, heat, light, sound, broadens domain mechanically sensitive materials. However, understanding nanomechanical aspects about these remains elusive. A comprehensive examination interplay among structures, deformation characteristics, responses essential further exploration. Such insights are crucial addressing intrinsic limitation "one-time use" associated deformation-induced properties, necessitating a focus on solid-state healing processes well. Recent investigations into inorganic-based ML systems applied free-standing light sources metamaterial design foreshadow future trajectory molecular-based systems. advancements aim facilitate secondary use generated photons efficient capture/transfer cues, enhancing optical output. Molecular stands poised make substantial contributions ongoing rapid progress mechanoscience due an expanding synthetic repertoire, heightened biocompatibility, precise "structural control" at macroscopic scales.

Emission from crystalline organic solids is often quenched by nonemissive energy-transfer deexcitation processes. While dispersion of fluorophores in polymers or other hosts has been used to enhance the emission intensity, this strategy results randomization guest orientation and optical losses at grain boundaries. Here, we report doping inherently single crystals anilinium bromide with three fluorescent molecules. The process equips crystal characteristics that tune blue deep orange. intensity can be reversibly modulated ferroelastic twinning, which causes material function as a multiemissive force sensor. This approach opens up new pathways manipulation emissive properties may have substantial implications for optoelectronic devices sensors.

In the past two decades, advancement of aggregation-induced emission (AIE) has greatly advanced our understanding organic luminescence and facilitated application luminescent materials. AIE luminogens (AIEgens) emit weakly in solutions but strongly aggregated states. This significant difference between states AIEgens shown that there is much to explore mesoscopic world (the intermediary phase). Accordingly, research paradigm aggregate science proposed. The path new materials relies not only on molecule syntheses also control molecular aggregation, which bridges gap solids. this Perspective, we outline three general strategies for managing aggregation stimulate ideas provide guidance controllable aggregation.
