3‐(9‐Carbazolyl)carbazoles and 3,6‐Di(9‐carbazolyl)carbazoles as Effective Host Materials for Efficient Blue Organic Electrophosphorescence

Linking topology in oligocarbazoles (see figure) has a strong influence on their electronic properties. 3(6),9′-linked oligocarbazoles exhibit unusual suppression of electronic coupling between units, leading to localized excited states and very small reduction of triplet energies (compared to the m...
