A new design of nonaggregated zinc(II) carboxyphthalocyanines with potential application in dye-sensitized solar cells has been developed. It is based on the introduction of bulky and rigid aryl groups at three 伪 positions of the macrocycle. The synthesis has been carried out following a convergent route in which the bulky aryl groups are introduced by a Suzuki鈥揗iyaura cross-coupling reaction on a preformed triiodophthalocyanine derivative. Two regioisomers of this 伪-triaryl-尾-carboxyphthalocyanine could be isolated by column chromatography.
