*Sublimation is a technique used to obtain ultra pure grade chemicals to get rid of mainly trace metals and inorganic impurities. Sublimation happens under certain pressure for chemicals to only go through two physical stages, from a solid sate to vapour (gas) and then the vapour condensed to a solid state on a cool surface (referred to as cold finger). The most typical examples of sublimation are iodine and dry ice. For more details about sublimation, please refer to sublimed materials for OLEDs and perovskites and our collection of sublimed materials.

Applications

Titanyl phthalocyanine (TiOPc), the family member of highly photosensitive phthalocyanine compounds, is one of the most successful leading materials used in the photocopying industry. Among various phthalocyanine semiconductors, oxotitanium phthalocyanine in the crystal form of phase-Y (Y-TiOPc) has attracted particular attention due to its high photosensitivity to NIR light. The quantum efficiency of Y-form TiOPc for photo carrier generation is reported to be almost 100% in high electric fields[2].

Titanyl phthalocyanine is used as a water photooxidation agent and is built into sensors for NO2 detection. It has also been made into devices for of organic light-emitting diodes (OLEDs) and organic photovoltaics (OPVs) with photon to current efficiency (PCE) over 4% reported by using TiOPc as the light-harvesting dye and C60 as the electron acceptor [3-6].
