SFB 1249: N-Heteropolyzyklen als Funktionsmaterialien

The SFB 1249 is an interdisciplinary Collaborative Research Centre at Heidelberg University with project partners at the Karlsruhe Institute of Technology (KIT), MPI for Solid State Research in Stuttgart, University of Kassel and the Heidelberg Institute for Theoretical Studies (HITS). It is funded by the German Research Foundation (DFG).

The aim of this SFB is the development of novel organic functional materials with specifically tailored electronic properties and their application as photoactive components and organic semiconductors. We focus on the molecular class of N-heteropolycycles, which provide a wide range of tunable structures. Research areas include Synthesis (A), Theory and Structure (B), and Material and Function (C).
