N–H bond. Compound 4 with a methylene spacer between the naphthalene and thiosemicarbazide moieties was deliberately designed as a fluorescent photoinduced electron-transfer anion (PET) sensor. However, the methylene spacer did not prevent delocalization of the HOMO orbital between the planar aromatic ring and the thiosemicarbazide unit as expected on the basis of the “fluorophore–spacer–receptor” PET
