空间拥挤的四芳基芘 1-3 可以通过 Suzuki 耦合轻松获得，在溶液和固态下均表现出非聚集（π 堆积）行为。 1-3 不易结晶的倾向及其适中的分子尺寸使其可用作 OLED 中的蓝光发射材料，并具有良好的器件性能。
The sterically congested tetraarylpyrenes 1-3, which can be readily accessed by Suzuki coupling, exhibit no-aggregation (pi-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.
