説明

Photocleavage reaction of triazatriangulene (TATA) leuco derivatives bearing axial substituents proceeded quantitatively in polar solvents with quantum yields (Φr) 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, Φr became less than 0.01.
