摘要:The invention relates to a phthalocyanine compound, which has a structure as represented by Formula I, wherein A represents a transition metal or a rare earth metal; R1 represents a phenyl group, a naphthyl group, or a C 4 -C 16 n-alkyl group. The aromatic phthalocyanine compound having the structure of Formula I provided in the invention contains a transition metal or a rare earth metal, and introduces a peripheral substituent into a linearly extended Ï€-conjugated system. It is relatively stabler at 400° C. or less and will be easily evaporated in vacuum to form a uniform thin film, and has good thermal stability, high chemical stability, and high mobility. The organic semiconductor device has the features of relatively fast on-off speed, relatively high on-off ratio, and strong reliability.
