Synthesis and self-assembly of structurally related mercapto- and isocyanoazulenes, including novel 2-mercapto-1,3-dicyanoazulene (4) and 2-isocyano-1,3-dicyanoazulene (5), are reported. Exposing 5 adsorbed on Au(111) to a solution of 4 displaces the isocyanoazulene monolayer with that of the mercaptoazulene as judged by νCN signatures of these films.
报告了结构相关的巯基和异氰基唑烯的合成和自组装,包括新型 2-巯基-1,3-二氰基唑烯(4)和 2-异氰基-1,3-二氰基唑烯(5)。将吸附在 Au(111) 上的 5 暴露于 4 的溶液中,根据这些薄膜的 νCN 信号判断,异氰基氮杂环烯单层与巯基氮杂环烯单层发生了置换。
