Polymethine Dye

Results are presented of time-resolved absorption investigations of energy transfer processes between a polymethine dye and an iron complex dye (dye E). For the first time the acceptor molecule transient absorption depletion generated by energy transfer from an excited donor was observed. The decay time of the acceptor deactivation (≈ 140 Ps) in the presence of the energy donor agrees very well with the S1-state lifetime of the energy donor.

Organic Framework

A redox active pyridine based covalent organic framework was synthesized and used as an electrode in faradaic supercapacitors. The pyridine units in the DAP-COF undergo a reversible redox reaction, leading to an increase in specific capacitance relative to both its electroactive monomer and a COF lacking redox-active groups.
