Two A–π–D–π–A carbazole derivatives differing in <italic>N</italic>-hexyl and <italic>N</italic>-isooctyl substituents were developed. They exhibited a prominent solvatochromic effect luminescence turn-on characteristics under mechanical force stimuli.
A new approach to cyclophane-based supramolecular mechanophores is presented. We report a mechanically responsive cyclic motif that contains two fluorescent 1,6-bis(phenylethynyl)pyrene moieties are capable of forming intramolecular excimers. The emission spectra dilute solutions this cyclophane and polyurethane elastomer into which small amount the mechanophore (0.08 wt %) had been covalently integrated dominated by excimer emission. Films cyclophane-containing also display considerable...
Real-time monitoring of the contents molecular oxygen (O2) in tumor cells is great significance early diagnosis cancer. At same time, photodynamic therapy (PDT) could be realized by highly toxic singlet (1O2) generated situ during O2 sensing, making it one most promising methods for cancer therapy. Herein, iridium(III) complex cored hyperbranched phosphorescent conjugated polymer dots with negative charges hypoxia imaging and efficient PDT was rationally designed synthesized. The incomplete...
The influences of conjugation on the third-order nonlinear optical (NLO) properties covalent organic frameworks (COFs) provide guidelines to design structures for desired applications.
Abstract Dimensionality of covalent organic frameworks (COFs), in terms 2D and 3D, must greatly influence their properties functionalities due to the different electronic porous structures, but still less investigated 20 years history. Herein, on basis imidization reaction phthalocyanine‐based tetraanhydride monomers with either 1,4‐phenylenediamine or 1,3,5,7‐tetra(4‐aminophenyl)adamantine, 3D imide‐bonded COFs sql pts topology have been prepared explore third‐order nonlinear optical (NLO)...
In this contribution, we finely tuned the singlet-triplet energy gap (ΔEST) of AIE-active materials to modulate their fluorescence, phosphorescence and delay fluorescence via rational molecular design investigated possible ways harvest triplet in OLEDs. Noteworthily, two molecules o-TPA-3TPE-o-PhCN o-TPA-3TPE-p-PhCN with larger ΔEST values (0.59 eV 0.45 eV, respectively) emitted efficient long-lived low temperature glassy solutions exhibited crystallization-induced room (RTP). Meanwhile, it...
Abstract Luminescent materials simultaneously exhibiting aggregation‐induced emission (AIE), superior luminous efficiency, and thermally activated delayed fluorescence (TADF) properties in amorphous phase are eagerly required for highly efficient nondoped organic light‐emitting diodes. In this contribution, an acridine/sulfone derivative, bis(3‐(9,9‐dimethyl‐9,10‐dihydroacridine)phenyl)sulfone (mSOAD), designed synthesized by combing a diphenylsulfone (DPS) core with...
A high molecular weight poly(arylene ynonylene) with an aggregation-enhanced emission characteristic was synthesized in yield by a newly developed polymerization route. Its can be turned 'on' hydrazine, as well 'off' picric acid, demonstrating the first fluorescent sensor that works for both hydrazine and explosives detection.
Four bipolar materials using 1,2,4-triazol derivative as an acceptor and carbazole a donor were synthesized. They can be used not only emitters to fabricate deep-blue OLEDs, but also hosts construct PhOLEDs.
Solution-processed white OLEDs based on a blue TADF dendrimer host and an orange iridium complex dopant achieved maximum EQE of 10.1% with low efficiency roll-off at high current density.
Propeller-shaped molecules have been recognized to display fantastic AIE (aggregation induced emission), but they can hardly self-assemble into nanostructures. Herein, we for the first time report that ionic complexation between a water-soluble tetrapheneyl derivative and an enzyme substrate in aqueous media produces propeller-shaped supra-amphiphile self-assembles responsive fluorescent vesicles. The was fabricated upon luminogen TPE-BPA myristoylcholine chloride (MChCl) media. MChCl filled...
Two slightly twisted A-π-D-π-A molecules were prepared to demonstrate that the red/near-infrared mechanoresponsive luminescence turn-on behaviors could be realized through mechanically disturbing their weakly/non-emissive metastable nanostructures, giving emissive amorphous aggregates with λem = 620 nm, ΦF 12% (h-DIPT) and 700 10% (DIPT), respectively.

Conventional solarizing seawater suffers from inefficiency and space constraints. Interfacial solar vapor generation (ISVG) presents an energy-efficient alternative, yet the scalability, adaptability, durability of a evaporator for practical use are remaining concerns. Herein, hydrogen-bond-repairing featuring reconstructed large-width channels is proposed ongoing solarization in ISVG.
