Optical electrochemical data show that increasing length leads to a decrease the optical band gap due parallel increase highest occupied molecular orbital (HOMO) level. Furthermore, subtle...
In recent years, monolayer organic field-effect devices such as transistors and sensors have demonstrated their high potential. contrast, electroluminescent are still in infancy. One of the key challenges here is to create an material that self-organizes a combines efficient charge transport with luminescence.
