A new BODIPY (4,4-difluoro-4-bora-3a,4a-diaza-s-indacene) was synthesized and investigated for photophysical and chemical properties based on donor-photoinduced electron transfer (d-PET) inhibition. Its sensing detection mechanism has been fluorescence turn-on involving d-PET blocking which was in-depth investigated by spectroscopy and electrochemistry, as well as by TD-DFT calculation. Strategically, d-PET was blocked by H-bonding from ethyl acetate and self-assembly of BDPPHOH via HO- and NO2-fragments in BDPPhOH.
