Scheme 4.10 Synthesis of push–pull SubPz
and Nc (Claessens et al. 2014). In contrast, the peripheral extension at the α,βpositions of SubPc has a smaller effect on the red-shift of absorption but endows
the inherent chirality to the molecule (Shimizu et al. 2011). Two diastereomers of
1,2-subnaphthalocyanine (1,2-SubNc) exhibited similar UV/vis absorption, fluorescence, and MCD spectra (Fig. 4.16). However, the CD intensity of the C 1 isomer is
one third of that of the C 3 isomer. On the basis of the band deconvolution analysis
