Background: Zn(II) meso-tetraphenylporphine  (chlorin free) is a synthetic porphyrin specialty chemical manufactured by Frontier Specialty Chemicals. Zn(II) meso-tetraphenylporphine has been used as an ionophore for a cyanide ion selective electrode.¹ Zn(II) meso-tetraphenylporphine  and quantum dots were used to modify colloidal silica beads  for colorimetric sensing of ammonia.²  The photophysical properties of Zn(II) meso-tetraphenylporphine and similar Zn(II) porphyrins have been reported.³ Zn(II) meso-tetraphenylporphine  acts as a initiator for free-radical polymerization by homomolecular triplet fusion.⁴
