— A series of modified 2‐phenylquinolines were synthesized and their absorption and emission spectral properties measured in order to determine the effect of structural modifications on excited states. It was hoped that modifications would sufficiently change excited‐state properties so that similar structural modifications in 2‐phenylquinolinemethanols would negate the phototoxicity of these compounds. The excited states of 2‐( o ‐hydroxyphenyl)quinoline, 11 H‐indeno[1,2‐b]quinoline, and l,4‐dimethyl‐5,6‐dihydrobenz[c]acridine proved to have properties different from those of normal 2‐phenylquinolines, and this effect was shown to be reflected in simple photochemistry of the dihydrobenzacridine. Absorption spectra provided information on conformational preferences for several of the derivatives.
