Check the paper attached. The authors have performed a proper study of different metal-phthalocyanines in a variety of solvents and their solubility, among other things.
Sigma Aldrich has iron-phthalocyanine solutions available, but their website is currently down.
Hope this can get you started, while someone knowledgeable in this field can provide you with a better/definitive answer.
Added later: Sigma Aldrich DOES NOT have solutions; I was wrong. Their website is now up and running, and I presume what they sell is a solid (1g or 10g).
Beside, the intersted paper provided by Sudarsan VenkatRamani, please, find in attach another intersting paper in Syntheses and Functional Properties of Phthalocyanines by Keiichi Sakamoto and Eiko Ohno-Okumura, Materials 2009, 2, 1127-1179; doi:10.3390/ma2031127
if Iron phthalocyanine can be dissolve in water,why you are looking for the organic solvent,used water it is better.it is cheap,available and it has no side effects.
Dissolution of phthalocyanine macrocycles depend on the functional groups or position of the substituents on the phthalocyanines. You can try THF, chloroform or dichloromethane etc.
