英文摘要：

Semiconductor circuits and their components play very important roles in the modern information society. However, silicon-based inorganic circuit will face the development bottleneck. Organic circuit has been considered as the potential candidate for next generation circuit due to its low cost, high transmittance and wide applications on the flexible substrates. Significant progress has been made on the organic circuits and their basic elements in the past few years. Moreover, some basic elements have already been put into practical applications. For example, organic light-emitting diode （OLED） has been shown as a new choice for the next generation display technique. In this review, we focus on the recent development of the system-level circuits, where the basic elements are classified into four types according to the functional properties, i. e., information collection, information processing, information storage and information output. We summarize the recent important advances in the basic elements of organic circuits such as organic field-effect transistor sensors, the basic logic gates, coding devices, signal conversion devices, flash memories, resistance-type memories, electronic paper, OLEDs, and organic light-emitting transistors. The key progresses of the devices based on the organic field-effect transistors are highlighted, including the the frontier researches, the optimization of electrical properties and main challenges.
