A mixed valent silicon compound is synthesized in a one-pot reaction. The mixed valency of the compound allowed reversible electromerism under the influence of Lewis-acid/base acting as external stimuli. A mono-silylene ligand could be transformed to bis-silylene by adding Cu^I salts. Upon removal of Cu^I salts, the bis-silylene motif reverts back to mono-silylene.

刺激响应硅烯：电聚作用诱导单硅烯和双硅烯之间的可逆转换


通过一锅反应合成混合价硅化合物。该化合物的混合价态在路易斯酸/碱作为外部刺激的影响下允许可逆电致聚合。通过添加铜盐，单亚甲硅烷基配体可以转化为双亚甲硅烷基。去除铜盐后，双亚甲硅基基序恢复为单亚甲硅基。
