Abstract

A series of three new seminaphthorhodamine analogs were synthesized via the condensation of 7-amino-2-naphthol and amino substituted hydroxy-benzophenones. Absorption, excitation, and emission spectra were taken in a variety of solvents and pH values. At biological pH, the molecules showed increasing Stokes shifts (from 40 to 95 nm) and longer wavelength emission in phosphate buffer with increased alkylation of the rhodamine nitrogen moiety. The fluorescent properties of the compounds were pH insensitive and variable in organic solvents. Two of the compounds exhibited significant emission at long wavelengths on the edge of the near infrared region of the electromagnetic spectrum.
