Unravelling the photobehavior of a 2,1,3-benzothiadiazole-based HOF and its molecular units: experimental and theoretical insights into their spectroscopic properties in solution and in the solid state

Revealing the photobehaviour of a new BTD-based HOF shows the occurrence of intramolecular charge-transfer and intermolecular proton-transfer photoevents leading to different emission spectra and lifetimes when compared to the molecular units.
