Materialists and chemists have thousands ways to design and synthesize organic semiconductors. However, our understanding about structure/composition/property correlation of these many soft semiconductors is seriously limited by complicated morphology that introduces energy disorders into materials; the extrinsic interference masks the intrinsic electronic structures of the materials we design. Through the technique of directed crystallization with the assistance of capillary force and nano-template, highly oriented polymer backbones can be achieved. And, I will uncover the role of ordered morphology in understanding of the macroscopic properties of these soft semiconductors. In addition to the science of controlling crystallinity, this will provide crucial knowledge for designing novel organic materials with exotic properties such as band engineering, amazingly small transport effective mass, high performance electronic devices, and many more opportunities to bringreal impacts in electronics industry.
