The synthesis of novel peripheral or non-peripheral tetra-2,6-dimethoxyphenoxy substituted metal free, zinc(II) and indium(III) phthalocyanines was achieved. The novel compounds were characterized by IR, UV-Vis, H-1 NMR, MALDI-TOF mass spectroscopies and elemental analysis as well. The effects of the substituent position and the influence of the variety of central metal ions in novel phthalocyanines, on their spectroscopic, photophysical (fluorescence quantum yields, fluorescence lifetimes) and photochemical (photodegradation, singlet oxygen) properties were also investigated in dimethylformamide (DMF). The phthalocyanines showed good singlet oxygen quantum yields, appropriate photodegradation and fluorescence behaviour. For this reason, they may be appropriate candidates Type II photosensitizers for photodynamic therapy of cancer. (C) 2015 Elsevier Ltd. All rights reserved.

The present disclosure provides a resin blend. The resin blend includes at least one diluent containing a single phthalonitrile functional group and at least one diphthalonitrile resin. Also provided are prepregs including the resin blend impregnated into continuous reinforcing fibers or a cloth. Similarly, the present disclosure provides a molding compound including chopped reinforcing fibers distributed in the resin blend. An article is also provided, which includes polymerization product of the resin blend. An alternative article includes a substrate and a layer of the resin blend disposed on the substrate. The diluent typically improves processability of the resin blend and lowers the softening temperature of the polymerization product of the resin blend.
