Background: Pd(II) 1,4,8,11,15,18,22,25-octabutoxyphthalocyanine is a phthalocyanine specialty chemical manufactured by Frontier Specialty Chemicals. A solid film consisting of neat Palladium (II) 1,4,8,11,15,18,22,25-octa-n-butoxyphthalocyanine and rubrene was excited at 730 nm resulting in infrared to visible photon upconversion via sensitized triplet-triplet annihilation1,2. Spectroscopic properties: abs: 737 nm (DMF), emission: 756 nm (DMF).3  A list of solubility, properties, and other data is given.Palladium (II) 1,4,8,11,15,18,22,25-octa-n-butoxyphthalocyanine was used as a photo thermal agent for the release of phosphorylated gemcitabine from theranostic nanoparticles for pancreatic cancer treatment.4 Palladium (II) 1,4,8,11,15,18,22,25-octa-n-butoxyphthalocyanine can be used as a infrared light sensitive photoredox catalysis by the mechanism of triplet fusion upconversion.A review of infrared to visible upconversion devices was published which includes Palladium (II) 1,4,8,11,15,18,22,25-octa-n-butoxyphthalocyanine.6
