题目Title:  Monodisperse and star-shaped organic semiconductors for energy saving photonic applications and super-fast data

       

内容摘要:

    

        Well-defined and monodisperse oligomers can be considered to be intermediate of conjugated ‘small molecules’ and polymers, and can feature the best of both sets of attributes. Precise HOMO/LUMO energy levels, high thermal stability, good solubility and excellent film-forming properties are common features that can be achieved in such materials. Moreover, the precise structure of the material is known (compared with polydisperse systems) and this makes our understanding of structure-property relationships much easier to establish.

        The synthesis and properties of some monodisperse conjugated star-shaped and linear structures will be presented in this talk, along with their integration into photonic and electronic devices. Applications of the resulting devices are presented and include white-light LEDs and visible light communications (Li-Fi), that promise highly energy efficient lighting and data that can stream at astonishing speeds of up to 1 Tb/s!
