dc.description.abstractThe paper reports on the synthesis and fluorescence characteristics of a novel benzanthrone fluorophore. It is configured as a ``fluorophore-spacer-receptor`` system able to act as a pH-probe via PET fluorescence sensing mechanism. Due to the tertiary amine receptor the novel probe shows ``off-on`` switching properties under transition from alkaline to acid media (FE = 16.3). The ability of the probe to detect metal ions in water/DMF (1:1, v/v) is evaluated by monitoring the changes of its fluorescence intensity. The presence of cuprum ion (Cu2+) only, among the tested metal ions (Cd2+, Co2+, Cu2+, Fe3+, Ni2+, Hg2+, Zn2+ and Ag+), is efficiently detected by fluorescence quenching mechanism. Due to the remarkable fluorescence changes in the presence of protons, hydroxide anions and Cu2+ ions the novel probe is able to act as a disabled-INH logic gate at a molecular scale.
