Fig. 5.75 Tetraboron complexes
Bis(pyrrolopyrrole) cyanines Bis(PPCy)s are selective NIR absorbers with very
narrow absorption bands, extremely high absorption coefficients, high photochemical
stability, and the lack of any strong absorption in the visible spectral range (Fig. 5.75a)
(Fischer et al. 2011b). Tetraboron complex 223 shows strong red fluorescence and
unipolar electron-transporting semiconductor characteristics (Fig. 5.75b) (Min et al.
2019).
