Web17 de set. de 2024 · On-surface self-assembly of 9,10-dicyanoanthracene (DCA) molecules on the Au (111) surface is studied to target honeycomb/kagome networks containing heavy-metal atoms with strong spin-orbit interaction. Coexisting close-packed islands of DCA molecules and Au-DCA coordination structures are found.
WebOn-surface chemical reaction has become a very powerful technique to conjugate small precursor molecules and several reactions have been proposed with the aim to fabricate functional nanostructures on surfaces. Here we present an unforeseen adsorption mode of 9,10-bis((trimethylsilyl)ethynyl)anthracene on a Cu(111)surface and the resulting one … WebDOI: 10.1016/J.CCLET.2024.04.022 Corpus ID: 99747998; On-surface construction of low-dimensional nanostructures with terminal alkynes: Linking strategies and controlling methodologies
Web22 de jan. de 2024 · In contrast to the conventional wet-chemistry method, on-surface bottom-up synthesis presents a promising approach for the fabrication of both unsubstituted ZGNs and functionalized ZGNs with atomic precision via surface-catalyzed transformation of rationally-designed precursors. WebThe conventional synthesis of cis-enediynes in solution typically involves multiple steps and various side reactions. For the first time, selective one-step synthesis of cis -enediyne from a single reactant is reported on a Ag(111) surface with a yield up to 90 %.
WebHoje · Synthesis of Boscalid (7): The biaryl compound 5 was prepared according to Table 2. The biological active Boscalid was prepared by the reaction of 2-amino-4-chlorobiphenyl ( 5 ) (203 mg, 1 mmol) with 2-chloronicotinoyl chloride ( 6 ) (1.02 mol equiv) in the presence of Et 3 N (2 mol equiv.) in 4 mL of CH 2 Cl 2 at room temperature for 30 min.
WebWith contributions by leading international experts, this book presents a detailed compilation of a new and very active field.
