文摘

The sterically congested tetraarylpyrenes 1-3, which can be readily accessed by Suzuki coupling, exhibit no-aggregation (-stacking) behaviorin both solution and solid states. The indisposed tendency of 1-3 toward crystallization and their moderate molecular dimensions permitexploitation as blue light emitting materials in OLEDs with respectable device performances.
