This study reveals the phenomenon of single-crystal nanooptomechanical transduction under specific conditions of light stimulation, along with the changes in molecular structure that occur during this process.
Single-crystal nanooptomechanical transduction occurs in [Ru(SO2)(NH3)(4)(H2O)]chlorobenzenesulfonate(2), 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 eta(1)-SO2 ligand photoconverts into an eta(1)-OSO photoisomer which, in turn, induces a 49.6(9)degrees arene ring rotation in its neighbouring counter ion.
