Controlled release and characterisation of photocaged molecules using in situ LED illumination in solution NMR spectroscopy

Photocaging is an attractive strategy to control molecular behaviour, for example, in chemical synthesis, interaction studies or photodynamic therapies. Here, we demonstrate that in situ illumination by the LED NMRtorch approach enables effective and controlled photocage release with simultaneous monitoring of subsequent reactions by solution NMR spectroscopy.
