Abstract: Organic photodetectors have attracted much attention in frontier science and technology fields
such as image display, optical communication and biosensing due to their tunable detection wavelength,
low-cost fabrication, and good compatibility with flexible/lightweight devices. As an important class of
photosensitive materials, phthalocyanines have great application potential in the photoactive layer, the core
functional layer of organic photodetectors, because of their narrow and tunable optical bandgap, excellent
physicochemical stability and high photogenerated carrier efficiency. Herein, the structure, properties, and
classification of phthalocyanines were firstly introduced. Next, the detection principle, basic structure and
photoelectric properties of photodetectors were briefly described with emphasis on the research progress
and influencing factors of different types of phthalocyanines in the preparation of photoactive layer, the
regulation of detection wavelength and the global optimization of device performance. Finally, the
development prospect of phthalocyanines in the field of organic photodetectors was discussed.
Key words: photodetectors; phthalocyanines; stability; photoactive layer; performance optimization
