Thiophen-2-yl and bithienyl substituted pyrazine-2,3-dicarbonitriles as precursors for tetrasubstituted zinc azaphthalocyanines

M?rkved, Eva H.,Andreassen, Trygve,Fr?hlich, Roland,Mo, Frode,Gonzalez, Susana V.

, p. 201 - 210 (2013/07/31)

Peripheral thiophen-2-yl substituents extend the macrocyclic conjugation of zinc(II)azaphthalocyanines, (ZnAzaPc), due to coplanarity between the two ring systems, and red-shifted UV-Vis Q-bands are observed. This lowering in energy is favourable for vari
