Abstract

We present a detailed kinetic study of photo-induced solid state linkage isomerism in the compound [Pd(Bu4dien)NO2]BPh4(Bu4dien = N,N,N’,N’-tetrabutyldiethylenetriamine) using in-situ photocrystallographic techniques. We explore the keyvariables that influence the photoconversion and develop a detailed kinetic model for the excitation and decay processesand the temperature dependence of the conversion rates. We show that by varying the temperature the lifetime of theexcited state can be varied over orders of magnitude, making these systems ideal test cases for the development of newtime-resolved X-ray diffraction methods. The kinetic model is used to build a numerical-simulation tool, which we use toexplore the practicalities of pump-probe single-crystal diffraction experiments with minute and second time-resolution.
