Near infrared absorption spectra (700-l 800 nm) of various lanthanide bis-phthalocyanines (PqLu, Pc2Yb, Pc\*Tm, Pc\*Dy) show two relatively intense bands (t,,, 5 lo4 M-' cm-'). The higher energy band is assigned to the les+alU transition of the radical macrocycle (PC-) while the lower energy one may
