Abstract

Photocleavage reaction of triazatriangulene (TATA) leuco derivatives bearing axial substituents proceeded quantitatively in polar solvents with quantum yields (Φ<sub>r</sub>) of up to 0.56. The photoreaction can easily be detected by the red color and yellow fluorescence originating from the photogenerated TATA cation. Electron-withdrawing groups on the axial substituent effectively suppress the photoreaction, in a particular case, Φ<sub>r</sub> became less than 0.01.
