Hydrogels have attracted widespread attention in anticounterfeiting due to their unique physical/chemical properties and designability. However, hydrogels' poor mechanical sluggish response chemical stimuli pose challenges for wide application. A fluorescent tough organohydrogel capable of freeform writing information is reported this work. By incorporation the monomer 7-methylacryloxy-4-methylcoumarin into polyacrylamide network a covalently cross-linked manner while intertwining with...
Buckybowls attract significant attention in chemistry and materials science owing to their unique features related both geometric electronic aspects. Doping the π-skeleton of buckybowls with main group elements results hetera-buckybowls, accordingly has a large influence on chemical physical properties. This account summarizes our research progress hetera-buckybowl trichalcogenasumanenes (TCSs), including synthesis, regioselective oxidations, transformation into various hetero polycycles...
Euphorpekone A (1) and euphorpekone B (2), two new diterpenoids, 3β-hydroxy-25-methyloxylanosta-8,23-diene, a triterpenoid (3), together with known triterpenoid, 3β,25-dihydroxylanosta-8,23-diene (4), were isolated from Euphorbia pekinensis Rupr. Their structures elucidated on the basis of UV, IR, 1D (1H, 13C, NOE) 2D (1H–1H COSY, HSQC, HMBC) NMR, HR-ESI-MS, X-ray diffraction analysis, CD method.
Abstract 2,3,4,6‐Tetrahydro‐1,6‐dithia[3‐ a ]azaphenalene (THDTAP) is heteropolycycle possessing two reactive sites for acylation. The regioselective acylation of THDTAP was achieved at the para and meta positions with respect to nitrogen atom under conditions AlCl 3 (1.3 equiv, 25 °C) (4 40 °C), respectively. A series ‐ ‐benzophenones having donor–acceptor‐type structure were then synthesized, in which benzoyl moieties serve as donor acceptor, Under typical McMurry reaction conditions, show...
Abstract Four tetraphenylethylenes ( 2 a – d ) containing an electron‐rich 2,3,4,6‐tetrahydro‐1,6‐dithia‐ 3a ‐azaphenalene (THDTAP) moiety have been synthesized. The show aggregation‐induced emission (AIE) with yellowish green photoluminescence (PL) in THF‐H O (v/v, 1:9) solution and the solid state. Compounds undergo 1,2‐migratory shift oxidative cyclodehydrogenation reactions to afford unexpected products 3 which display PL CH Cl are non‐emissive intensities of clearly enhanced presence...
Summary of main observation and conclusion The electron‐donating unit 2,3,4,6‐tetrahydro‐1,6‐dithia‐3a‐azaphenalene (THDTAP) was introduced onto terpyridine (TPy) to give a donor‐acceptor (D‐A) type TPy‐ligand (compound 2 ). Upon selective oxidation two sulfur atoms on the THDTAP moiety , ligands 3 — 6 were created. electronic structures evaluated by theoretical, electrochemical, spectroscopic investigations. brings significant influence ability moiety, subsequently, leads fine modulations...
Integrating different functions in one material will decrease the volume, responding time, and price of device. Polyimides (PIs) are optimal candidates because excellent flexible mechanics, thermal stability, transparent properties. In this work, a series multifunctional PIs were designed synthesized from novel functional triarylamine for electrochromic (EC) The show promising application EC with efficiency 205 cm2 C-1, memory devices ON/OFF ratio 3.7×104, photodetectors limit being 0.07 V....
Developing a shape memory polysiloxanes possessing superior mechanical properties, antibacterial qualities, and exceptional self-healing capabilities has become significant obstacle for the development of smart materials. We tackled this challenge by modifying using N-acetylcysteine (NACL) photosensitive molding with dynamic borate ester crosslinker (S-BDB). The resultant polysiloxane exhibited remarkable tensile strength up to 4.7 MPa. By utilizing hydrogen bonds grafted NACL S-BDB heal...
2,3,4,6-Tetrahydro-1,6-dithia[3-a]azaphenalene (THDTAP) is a heteropolycycle possessing two active sites for acylation. The regioselective acylation of THDTAP was conducted at the para and meta positions with respect to nitrogen atom, resulting in series para- meta-substituted benzophenones having donor–acceptor-type structure. benzophenone derivatives are distinct chemical reactivity photophysical properties. para-Substituted show reversible OFF/ON fluorescence upon acidification...
