Curved π-Conjugated Dehydrobenzoannulene as an Electron Acceptor Enabling Fluorescence and Electrochemiluminescence Emission
Using dehydrobenzoannulene as an acceptor, two curved π-conjugated electron donor-acceptor architectures were concisely synthesized, and an unexpected deshielding effect was observed in the annulene fragment. Anomalously, the π-extended homologue exhibited blue-shifted fluorescence. Intriguingly, stunning and stable electrochemiluminescence emissions were first discovered in nonaromatic annulene derivatives. Finally, based on those electrochemiluminescence properties, a highly efficient sensor for detecting dopamine was constructed. This work provides new insights into molecular carbons and promotes the development of sensing in biological analysis.
