An enhanced photoluminescence is observed upon addition of organic guests to the trimeric macrocycle (see picture; tpy=2,2′:6′,2″‐terpyridine). The use of a short alkyne bridge has enabled the rigid trimer and the smaller dimer to be prepared with controllable cavity sizes. A better redox communication between the Ru centers in the dimer is also observed.
