Synthesis, electronic and photophysical properties of a bisacridinium-Zn(II) porphyrin conjugate

Multi-Responsive Eight-State Bis(acridinium-Zn(II) porphyrin) Receptor

“…N-Substituted acridinium and porphyrin moieties represent appealing multi-responsive units that respond to chemical and redox signals by reversibly modifying their shape and/or their chemical and optical properties. , Their combination can lead to fast photoinduced electron transfer processes, and their integration in various supramolecular systems gives rise to sensing and actuating properties . Since the seminal work of Kubo and his group, receptors pre-organizing porphyrin cores coupled to secondary recognition units or switches also showed their ability to modulate their interaction with guests as the result of a large-amplitude motion .…”
