Excitonic processes in multifunctional organic semiconductors for application in organic-light emitting transistor

In this thesis, I report on a comprehensive study about the photo-physical properties both in solution and in solid-state of a new thiophene based material (2,2’-(2,2’-bithiophene-5,5’-diyl)bis(5-butyl-5H-thieno[2,3-c]pyrrole-4,6)-dione (T4DIM) which shows an ambipolar semiconducting behavior together with electroluminescence in single-layer OLET device architecture[14
