Tetrabenzo[5.7]Fulvalene: A Forgotten Aggregation Induced-Emission Luminogen

09 August 2019, Version 1
Working Paper
This content is a preprint and has not undergone peer review at the time of posting.

Abstract

Tetrabenzo[5.7]fulvalene, one of the first recognized stable members of mixed fulvalenes, has attracted widespread interest for its remarkable structure. However, little has been known about its photoactivity, most likely owning to its very weak luminescence in solution state. Here we show for the first time that this compound exhibits aggregation-induced emission (AIE) properties. Its photoluminescence and X-ray crystal structure reveal an interesting mechanism of AIE phenomenon.
