Acid And Base

The fluorescence of N-methyl-1-naphthymethylamine (NA) was reversible modulated by acid and base based on switching photoinduced electron transfer (PET) process, which constituted a reversible on –off switch. However, addition of a calix [4] arene-spiropyran (Calix-2sp) derivative, which has absorption from 200 nm to 400 nm, caused that the fluorescence of protonated NA (NAH) was quenched and it could not be return to its initial high value by means of addition of acid again. Thus, the system made up of an INHIBIT logic gate.
