    摘要: This invention relates to indole phthalein indicator dyes including phthalides and naphthalides wherein one of the indol-3-yl radicals is substituted with a hydrogen-bonding group on a carbon atom adjacent to the nitrogen atom of the indole ring. In a preferred embodiment, one of the indol-3-yl radicals is substituted with a hydrogen-bonding group and the other indol-3-yl radical is substituted with a hydrogen-bonding group or with an electron-withdrawing group. These indicator dyes, especially those of the preferred embodiment, possess a relatively high pKa and a relatively broad absorption spectrum in the visible range.
