Material Description

β-Titanium phthalocyanine (TiOPc), CAS number 26201-32-1, 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]. β-Titanium phthalocyanine is used as a water photo-oxidation 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].
