Tuning J-type dimers of non-peripherally substituted zinc tetra-4- tert-butylphenophthalocyanine

It was found, by UV–vis and TOF-MS, that the head-to-tail dimers of non-peripherally substituted zinc tetra-4- tert-butylphenophthalocyanine are inclined to form in non-coordinated solvent, e.g. chloroform and especially in dilute solution under 1.25 × 10 −6 mol/mL. The aforementioned dimers in solu...

Summary:It was found, by UV–vis and TOF-MS, that the head-to-tail dimers of non-peripherally substituted zinc tetra-4- tert-butylphenophthalocyanine are inclined to form in non-coordinated solvent, e.g. chloroform and especially in dilute solution under 1.25 × 10 −6 mol/mL. The aforementioned dimers in solution can be tuned by altering concentration or adding coordinated solvent, e.g. methanol, which might be further improved to a practical strategy for preparation of J-aggregates in the future.
