An anthracene-based molecular crystal with a unique “slipped herringbone” packing motif has been developed by delicate crystal engineering through terminal tert-butylation. Appropriate exciton-exciton coupling/electron-phonon coupling originating from the unique crystal packing induces a remarkably strong solid-state emission (photoluminescence quantum efficiency, Φ_F=74.9 %) and efficacious charge transport (carrier mobility, μ=5.0 cm² V⁻¹ s⁻¹).

通过末端叔丁基化调节晶体堆积以增强蒽基分子晶体中的固态发射和有效电荷传输

通过精细的晶体工程通过末端叔丁基化开发了一种具有独特“人字形”包装图案的蒽基分子晶体。源自独特的晶体堆积的适当的激子-激子耦合/电子-声子耦合诱导了非常强的固态发射（光致发光量子效率，Φ _F = 74.9 %）和有效的电荷传输（载流子迁移率，μ = 5.0 cm ² V ^{- 1} 秒^-1 )。
