Electrophilicsubstitutionreactions of sumanene were studied. Mono-, di-, and trisubstituted sumanenes were selectively prepared with the separation of all regioisomers. The regioselectivity was p...

The first sumanene–ferrocene probes for efficient and selective caesium cation (Cs+) recognition are reported. The working mechanism of the sumanene moiety as the sensing unit was based on the site-selective cation–πinteraction in its neutral state. The interactions with Cs+ were characterized by high association constant values together with low limits of detection.
