Covalently Attached Porphycene–Ferrocene Dyads: Synthesis, Redox-Switched Emission, and Observation of the Charge-Separated State
2016-01-04T00:00:00Z (GMT) by
Two new porphycenes functionalized with ferrocenyl pendants have been synthesized and characterized spectroscopically and structurally. The porphycene-based emission in porphycene–ferrocene dyads was switched on and off by the reversible control of the ferrocenyl pendant redox states. Transient absorption spectroscopy with a femtosecond laser-pulsed technique has successfully detected the picosecond charge-separated excited state of the dyad upon Q-band excitation of the porphycene ring.
