We demonstrate for the first time that the charge neutral anthracene based fluorescent sensors 1a–c, having an aromatic or aliphatic thiourea moiety as an anion receptor, show ideal PET sensor behaviour where the anthracene fluorescence emission is selectively quenched upon titration with AcO−, H2PO4− and F− but not by Cl− and Br− in DMSO.
