Efficient and Stable Blue Electrogenerated Chemiluminescence of Fluorene-Substituted Aromatic Hydrocarbons

Efficient and Stable Blue Electrogenerated Chemiluminescence of Fluorene-Substituted Aromatic Hydrocarbons

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. Fluorene‐based DPA (1) is characteriz...

Zusammenfassung: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. Fluorene‐based DPA (1) is characterized by a highly efficient and stable blue electrogenerated chemiluminescence (ECL).
