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