The research projects within Ottosson Group
Focus is given to silenes with reversed Si=C bond polarities (Sið-=Cð+) as these, for example, give higher chemoselectivity in reactions with (hetero)dienes than naturally polarized (Sið+=Cð-) silenes. The goal is applications of these reactions in selective organic synthesis. Applications of Si=C bonded compounds in molecular electronics are also being examined.
In this project area we exploit the reversal of the electron counting rules for aromaticity and antiaromaticity in the lowest triplet and singlet pp* excited states annulenes as compared to their electronic ground state. We have shown that a series of properties are varied through the mutual change in ground and lowest excited state aromaticity.
With focus on charge transport through compounds with unusual conjugation topologies, and in collaborations within the U3MEC constellation lead by Dr. Ottosson, development of new rigid molecular junction set-ups, novel anchor groups, and much more.
