A simple azido-substituted fluorescent sensor AHBO showing a selective turn-on response to cysteine (Cys) and glutathione (GSH) over homocysteine (Hcy), sulfide and other amino acids has been constructed, which is based on the mechanism of selective nucle

This work describes the synthesis of photoactive proton transfer compounds based on the benzazolic core containing the azide group. The compounds present absorption in the UV region and fluorescence emission in the visible region of the spectra with large

New lipophilic dyes were synthesized from a fluorescent precursor and used to produce photoactive liposomes and ethosomes made of different phospholipids. The lipophilic dyes absorbed in the ultraviolet region due to π-π* transitions and had a dual fluorescence emission in the violet-yellow regions, depending on solvent polarity. The long alkyl chain lipophilic dyes had a narrow emission band with a very regular shape, and their photophysical behaviour indicates that these dyes were inserted into the lipid bilayer. The dye with short alkyl chain appeared to be in a polar environment, which indicated this fluorophore experienced a more hydrophobic environment. Fluorescence titration experiments were also performed with this compound and the partition coefficient was determined, which showed higher values than those found in the literature for similar intramolecular proton transfer dyes, likely due to better interaction between this dye and the phospholipids, due to the alkyl chain present in the dyes.
