Self-assembly of Organic Semiconductor Molecules Regulated by Multiple Molecular Interactions

　　As amino acids and their corresponding polymers have specific chiral centers, various functional groups, hydrogen bonds and controllable secondary structures, thus they are often used as building blocks to tune and optimize the supramolecular structures. Meanwhile, degree of ordered molecular arrangements has a significant effect on the physical properties of organic semiconducting materials. Therefore, it remains as a great challenge to improve the degree of aggregates’ order through simple modifications. In this part, we make full use of the controllably multiple molecular interactions of amino acids to prepare functional and fine-tuned supramolecular structures and study the self-assembly behaviors and mechanisms. Furthermore, we are able to have a deep insight of the relations between molecular structures (supramolecular structures) and properties. Through molecular design, synthesis, controllable self-assembly and applications, we find it applicable to regulate the assembled structures via introducing amino acids and oligopeptides.
