The synthesis and characterization of two soluble, unsymmetrical nickel phthalocyanines with one aldehyde group in the α‐ ( 10b ) and β‐position ( 10a ), respectively, is reported. The β‐functionalized phthalocyanine (Pc) ( 10a ) was used in a Wittig reaction to afford the first "real" bisvinylene‐phenylene‐bridged bisphthalocyanine 11 . The properties of the new Pcs are compared with those of the corresponding tribenzonaphthoporphyrazino (TBNP) nickel analogues 1 and 3 .
