In recent years, organic semiconductors have shown broad application prospects in the fields of organic field effect transistor (OFET), organic photovoltaic (OPV), and organic light emitting devices (OLED) due to their adjustable molecular structure, flexible processing, and low cost. However, the contradiction between high mobility and excellent photoelectric performance is still the core problem restricting its development. Based on the research progress of typical organic semiconductor systems in recent years, this paper systematically analyzes the molecular design strategies, crystallization control methods, and the influence mechanism on photoelectric properties of high mobility organic semiconductors. In the theoretical part, the molecular structure characteristics, carrier transport mechanism, doping, and interface engineering principles of organic semiconductors are described. In the part of performance comparison, the mobility, luminous efficiency, and device performance of typical material systems are compared. According to previous studies, through molecular conjugate structure optimization, crystal orientation control and Interface Engineering collaborative design, the carrier mobility can be significantly improved and the photoelectric performance can be taken into account, which provides theoretical guidance for high-performance organic optoelectronic devices.
