Synthesis and Properties of Functional Materials C11

3D Printing Functional Structures based on N-Heteropolycyclic Derivatives

Prof. Dr. Eva Blasco – IMSEAM, Uni HD

Project Description

Within this project, we explore N-heteropolycycles as versatile building blocks for the fabrication of precise and functional 3D microstructures. Owing to their high fluorescence quantum yields, selected N-heteropolycycles are employed to realize high-resolution, multicolor 3D structures via two-photon laser printing. We design new photopolymerizable N-heteropolycyclic compounds with tunable emission properties, enabling controlled red, green, and blue fluorescence through targeted molecular modification. Twisted tetraazaperylene derivatives serve as red and green emitters, while new N-heteropolycyclic systems are investigated for blue emission. Their two-photon absorption properties are systematically studied. These structures showcase potential in applications including high resolution displays and anti-countering. In addition, we plan to investigate the integration of chiral emitters into different 3D matrices, with a systematic study of their chiroptical properties.
