The research work mainly uses molecular design and crystal engineering to realize the controlled growth of organic semiconductor crystals. From the preparation of large-size, high-purity and low-cost organic single crystals to the controlled growth of ultra-thin and two-dimensional organic single crystals and organic eutectic, a series of studies have been carried out to realize the regulation of the proportion, dimension, size and charge transfer degree of organic crystals. The problems of effective charge transport and precise control of non-covalent bond interaction are overcome, and the construction and application of high performance organic single crystal FET are realized.
