Seven new fluorescent 2-R-naphtho[2,3-d]oxaphospholes (R-NOPs) (4a-g; R = Bu-t (a), Ad (b), C6H5 (c), 4-MeC6H4 (d), 4-ClC6H4 (e), 4-BrC6H4 (f), 4-MeOC6H4 (g)), have been synthesized by cyclocondensation reactions of benzimidoyl chlorides with 3-phosphino-2-naphthol (3). The compounds were characterized by multinuclear NMR, UV-vis, and fluorescence spectroscopy. Compounds 4a-d and 4g were characterized by cyclic voltammetry experiments. The solid state structures of compounds 4b and 4d were also determined by single-crystal X-ray diffraction experiments.
