摘要：

(Figure Presented) Properly shielded: The fluorene groups used as capping agents for new diphenylanthracene (DPA), pyrene, and anthracene derivatives impart steric hindrance which prevents interchromophore interactions, giving these molecules high photoluminescence quantum yields. FIuorene-based DPA (1) is characterized by a highly efficient and stable blue electrogenerated chemiluminescence (ECL). © 2009 Wiley-VCH Verlag GmbH & Co. KGaA.
