Abstract
Hemipiperazines are an emerging class of robust molecular photoswitches based on a 2,5-diketopiperazine scaffold. We resolve the excited-state pathway responsible for efficient photoisomerisation of a model hydrogen-bonded hemipiperazine photoswitch using ultrafast time-resolved infrared spectroscopy and temperature-dependent fluorescence measurements.
