Crystal Engineering for Molecular Organic Semiconductors

Final Report Summary - CEMOS (Crystal Engineering for Molecular Organic Semiconductors)

The CEMOS project was dedicated to the development of strategies to control the self-assembly and crystallinity of organic semiconductors via molecular engineering. The outcome of the project was the demonstration of three new classes of materials: Class 1- Nucleation promotors, Class 2- Compatibilizers, and Class 3- Flexibly linked organic semiconductors. Overall the results show that the rational molecular engineering of organic semiconductors offers a powerful method to control crystalline arrangement, promote crystallite nucleation, compatibilize disparate phases, and plasticize inelastic materials. The developed materials have made important advances in the development of organic transistors and solar cells, importantly increasing their stability and ability to be processed by novel “green” approaches.
