Imidazopyridine als neue Materialien

Imidazopyridines as new materials


Because of their biological and photophysical properties imidazo[1,5-a]pyridines 1 belong to an important class for both material chemistry and pharmaceutical industry.  There are different technical applications for example OLEDs1 and FETs2 and different pharmaceutical applications for example as HIV-protease inhibitors3 and cardionic agents4.





We are looking for a new, economical and efficient method to synthesize different imidazo[1,5-]pyridines. In the literature different methods are already known, but most of them depend on long reactions times or toxic reagents.



Scheme 1: Reaction of ketones and amines to imidazo[1,5-a]pyridines


At the same time the investigation of optical and electronical properties of imidazo[1,5-a]pyridines is another important field of our research. For that reason we have a close cooperation with the working group of Professor Derck Schlettwein (Institute of Applied Physics, University Giessen).
