Abstract A series of bipolar transport host materials: 2,5‐bis(2‐(9 H ‐carbazol‐9‐yl)phenyl)‐1,3,4‐oxadiazole ( o ‐CzOXD) 1 ), 2,5‐bis(4‐(9 p 2 2,5‐bis(3‐(9 m 3 ) and 2‐(2‐(9 ‐carbazol‐9‐yl)phenyl)‐5‐(4‐(9H‐carbazol‐9‐yl)phenyl)‐1,3,4‐oxadiazole op 4 are synthesized through simple aromatic nucleophilic substitution reactions. The incorporation the oxadiazole moiety greatly improves their morphological stability, with T d g in range 428–464 °C 97–133 °C, respectively. ortho meta positions...
Accurate and up-to-date road maps are of great importance in a wide range applications. Unfortunately, automatic extraction from high-resolution remote sensing images remains challenging due to the occlusion trees buildings, discriminability roads, complex backgrounds. To address these problems, especially connectivity completeness, this article, we introduce novel deep learning-based multistage framework accurately extract surface centerline simultaneously. Our consists three steps:...
Two series of polyurethanes (P1−P10) containing NLO chromophores as side chains were prepared, in which the size isolation groups was changed from small atoms to much larger such carbazolyl groups. The polymers well characterized. tested properties demonstrate that values and poling efficiency are not always improved with increasing spacer, for a given chromophore moiety, there is suitable group present boost its microscopic β value possibly higher macroscopic property efficiently.
Three new carbazole copolymers, poly(9-(2,5-diarene-[1,3,4]oxadiazole)-carbazole-alt-9-(2-ethylhexyl)-carbazole-3,6-diyl)s (P1), poly(9-(2,5-diarene-[1,3,4]oxadiazole)-2, 7-carbazole-alt-9-(2-ethylhexyl)-3, 6-carbazole-diyl)s (P2), and poly(9-(2,5-diarene-[1,3,4]oxadiazole)-carbazole-alt-9-(2-ethylhexyl)-carbazole-2,7-diyl)s (P3), were synthesized by the Suzuki coupling reaction. The copolymers characterized 1H NMR, 13C elements analysis, their molecular weights estimated using gel...
A series of morphology-stable carbazole-based iridium(III) complexes with green to red emission have been prepared and characterized by elemental analysis, nuclear magnetic resonance, mass spectroscopy. Their thermal, electrochemical, electronic absorption, photoluminescent properties studied. Highly efficient polymer light-emitting devices using these as dopant emitters, both non-conjugated (PVK) conjugated polymer, polyhedral oligomeric silsesquioxane-terminated poly(9,9-dioctylfluorene)...
Abstract With the continuous development of economy, engineering construction is developing towards deep high-stress area, and problems large-deformation are becoming more serious. Anchoring grouting a very effective support reinforcement method. The anchoring materials used in project mainly cement paste mortar. characteristics material have decisive influence on effect. However, it difficult for existing to satisfy requirements strength deformation at same time, improvement urgently...
By employing a rhodium-Duanphos complex as the catalyst, β-alkyl (Z)-N-acetyldehydroamino esters were smoothly hydrogenated in highly efficient and enantioselective way. Excellent enantioselectivities together with excellent yields achieved for series of substrates. An approach synthesis intermediate orally administered anti-diabetic drugs Alogliptin Linagliptin DPP-4 inhibitor class was also developed.
Drawing and updating road networks are both time-consuming labor-intensive. Deep learning technology high-resolution remote sensing images have provided opportunities for automatic extraction. However, recent convolutional neural network (CNN) based segmentation methods shown serious problems on connectivity; tracing with single starting point perform well in connectivity but often result part areas unreached. We propose a multiple points tracer which benefits from methods. compare our...
Abstract The synthesis and structural characterization of a series novel, fluorinated poly(phthalazinone ether)s containing perfluorophenylene moieties are described. monomers, 4‐(4′‐hydroxyaryl)phthalazin‐1(2H)‐ones ( 2a – 2d ), were conveniently efficiently synthesized from phenols phthalic anhydride in two steps via 2‐(4′‐hydroxybenzoyl)benzoic acids, which first obtained by the Friedel–Crafts reaction good yields with high stereoselectivity then converted into fusion hydrazine. All...
