Analogues of N,N-dimethyladenine exploiting both thieno-and isothiazolo-pyrimidine cores were modified with 3-subsituted azetidines to yield visibly emissive and responsive fluorophores. Ribosylation of the difluoroazetidino-modified nucleobase yielded an emissive nucleoside that displayed a substantially lower emission quantum yield in water, compared to the precursor nucleobase. The impact of the
