🧩Application of 11H-Benzo[b]fluoren-11-one CAS No.: 3074-03-1

1. Organic Optoelectronic Materials

Acts as the core skeleton of dual-state emission (DSE) fluorophores, develops OLED light-emitting layer materials, and relieves the aggregation-caused quenching (ACQ) defect of traditional fluorescent molecules.

It applies to organic semiconductors and light-harvesting materials, and meets the application demands of solid-state luminescence and optoelectronic devices.

2. Fluorescent Probes and Bioimaging

It constructs high-stability fluorescent probes for cell imaging and subcellular organelle labeling, with excellent photostability and high quantum yield.
Served as molecular sensors to detect metal ions and small organic molecules in the environment.

3. Pharmaceutical & Chemical Intermediates

It works as a key skeleton for drug research and development, and synthesizes polycyclic aromatic hydrocarbon derivatives with anti-tumor and anti-inflammatory activities.
It supports organic synthesis to prepare fused aromatics, functional dyes and optoelectronic intermediates.
