Abstract

A series of pyrrole/polycyclic aromatic unit hybrid fluorophores was developed by a two- stage synthetic strategy. Their central aryl-substituted pyrrole cores were constructed by a Paal− Knorr pyrrole synthesis reaction. The reaction conditions and mechanism are also discussed in detail. End-capping triflate onto the central pyrrole core enables the core to incorporate various polycyclic aromatic units. The Buchwald− Hartwig amination reaction ...
