Abstract

The chelation dynamics of three new [Cr{?6-C6H5C(O)R}(CO)3] complexes 1 (R = CH2(SCH3)), 2 (R = CH(SCH3)2), and 3 (R = C(SCH3)3) in room temperature heptane, THF, and acetonitrile solutions have been investigated on the picosecond to millisecond timescale by UV-pump IR-probe transient absorption spectroscopy. This study highlights how subtle structural changes may be used to tailor picosecond processes for the design of ultrafast molecular switches.
