Abstract

Single-crystal nanooptomechanical transduction occurs in [Ru(SO)(NH)(HO)]chlorobenzenesulfonate, reaching maximal levels within 40 s at 100 K when photostimulated by 505 nm light. Its in situ light-induced crystal structure reveals the molecular origins of this optical actuation: 26.0(3)% of the η-SO ligand photoconverts into an η-OSO photoisomer which, in turn, induces a 49.6(9)° arene ring rotation in its neighbouring counter ion.

摘要

单晶纳米光机械转导发生在[Ru(SO)(NH)(HO)]氯苯磺酸盐中，当用 505nm 光光刺激时，在 100K 下 40 秒内达到最大水平。其原位光致晶态结构揭示了这种光致动的分子起源：26.0(3)%的η-SO 配体光转化为η-OSO 光异构体，进而诱导其相邻反离子的芳环旋转 49.6(9)°。
