A new family of discrete hexakis-pillar[5]arene metallacycles with different sizes have been successfully prepared via coordination-driven self-assembly, which presented very few successful examples preparation multiple pillar[n]arene derivatives. These newly designed were well characterized one-dimensional (1-D) multinuclear NMR (1H and 31 P NMR), two-dimensional (2-D) 1H–1H COSY NOESY, ESI-TOF-MS, elemental analysis, PM6 semiempirical molecular orbital methods. Furthermore, the host–guest...

Well-defined olive-shaped Bi(2)S(3)/BiVO(4) microspheres were synthesized through a limited chemical conversion route (LCCR), where BiVO(4) and thioacetamide (TAA) used as precursors sulfur source, respectively. The as-synthesized products characterized by X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM), high-resolution transmission microscope (HRTEM), photoelectron spectra (XPS), UV-visible diffuse-reflectance spectroscopy (UV-vis DRS), photoluminescence (PL)...

Vein graft occlusion is deemed a major challenge in coronary artery bypass grafting. Previous studies implied that the no-touch technique for vein harvesting could reduce rate compared with conventional approach; however, evidence on clinical benefit and generalizability of scare.From April 2017 to June 2019, we randomly assigned 2655 patients undergoing grafting at 7 hospitals 1:1 ratio receive or approach harvesting. The primary outcome was computed tomography angiography 3 months...

By simple ligand exchange of the cationic transition-metal complexes [(Cp*)M(acetone)3 ](OTf)2 (Cp*=pentamethylcyclopentadienyl and M=Ir or Rh) with pillar[5]arene, mono- polynuclear pillar[5]arenes, a new class metalated host molecules, is prepared. Single-crystal X-ray analysis shows that charged cations are directly bound to outer π-surface aromatic rings pillar[5]arene. One triflate anions deeply embedded within cavity trinuclear which different host-guest behavior most pillar[5]arenes....

Organic diradicaloids usually display an open-shell singlet ground state with significant diradical character (y0) which endow them intriguing physiochemical properties and wide applications. In this study, we present the design of nitrogen-centered diradicaloid can reversibly respond to multiple stimuli tunable chemo-physical properties. 1a was successfully synthesized through a simple high-yielding two-step synthetic strategy. Both experimental calculated results indicated that displayed...

Identifying quantitative trait loci (QTL) for yield traits using single-segment substitution lines (SSSL) is essential both targeted breeding and functional analysis of key genes. Here, a wide-grain rice chromosome segment line (CSSL), Z708, carrying four segments from Jinhui35 in the genetic background Xihui18, was used to identify QTL associated with grain size. Seven yield-related ( qGW4 , qRLW4 qGWT4 qGW5 qRLW5 qGWT5 qGPP5 ) were identified on fourth fifth chromosomes Z708. Subsequently,...

Summary of main observation and conclusion Photoswitchable or photoactivatable fluorescent species have been found wide applications within supramolecular chemistry materials science. In this study, we successfully constructed two highly emissive Pt(II) metallacycles from the diarylethene ligands via coordination‐driven self‐assembly. Different most known metallacycles, obtained displayed “turn‐on” fluorescence switching. They are non‐fluorescent in solution, but they emit yellow orange...

Abstract Herein, we report the successful construction of a new family dual stimuli‐responsive AIE cross‐linked supramolecular polymer through strategy hierarchical self‐assembly. A novel dipyridyl donor building block G1 containing tetraphenylethylene (TPE) moiety was designed and synthesized. Notably, two nitrile units were attached onto , which employed as guest for further host‐guest interaction with pillar[n]arene derivatives. The rhomboidal metallacycle G2 four firstly constructed...
