In this report, we introduce a relatively simple setup that can be used to determine QYs of molecular switches without the need for actinometry, by combining fibre-coupled LEDs with a commercially calibrated thermopile detector. Secondly, we present a promising semi-automated method for extracting the molar absorptivities of the meta-stable isomer from just the UV-vis absorption data. Azobenzene was chosen as the model compound for testing, as the recent work by Vetráková et al. and Ladányi et al. has provided us with very reliable molar absorptivities and QYs to use for validating our methods.
