Light‐Promoted Basic Nitrogen Unmasking in Arene Ruthenium Complexes Derived from Z ‐Configured 2,2′‐Azobispyridine

Abstract Two novel 2,2′‐azobispyridine derivatives bearing N ‐dialkylamino substituents at position 4,4′ were synthesized and their E – Z photoswitching behavior was characterized by combination of 1 H‐ and 13 C NMR spectroscopy, UV–Vis absorption…

Photoinduced Electron Transfer in Clicked Ferrocene‐BODIPY‐Fullerene Conjugates

Abstract Ferrocene‐BODIPY (Fc‐BDP) conjugates in which one or two ferrocene entities are linked to the β‐positions of the BODIPY core by an ethynyl bridge have been developed. These derivatives were easily and efficiently grafted onto a dual…
