A similar isotherm shape is observed for SA-P-BP, starting the water uptake at p/p0 = 0.7. Al-P-BP exhibits a continuous water uptake from p/p0 = 0.6 -1.0 and a comparable amount of adsorbed water like SA-P-BP with respect to the disposable specific surface area. The Ru-loaded macroligands underwent catalytic examinations, regarding their activities as well as their stabilities over three consecutive recycling runs (Fig. ). The TFMSA-catalyzed macroligand synthesis does not result in an active Ru-loaded catalyst, evincing low productivities in the first run and a slight decrease over the consecutive runs. Al-P-BP-Ru exhibits the highest initial activity of the three catalysts, accompanied by a continuous deactivation, which results in a significant loss of productivity between the first and the second run. In contrast, the productivity of Fe-P-BP-Ru in the first run is 25 % lower after 5.5 hours, though its deactivation is retained.
