Abstract

Thermally reversible photochromic spiro-acridans have been synthesized for the first time. They exhibit high ring opening efficiencies. As the formed zwitterions do not possess a merocyanine structure their lifetime is in the range of milliseconds to seconds. An observed side reaction can be avoided by suitable substitution of hydrogen atoms.
