Dendrimers with boronic ester end-groups and an iron porphyrin core were synthesized and characterized. The dendrimer termini were reversibly exchanged by the addition of appropriate diol molecules. According to molecular dynamics (MD) simulations, the exchange of termini may lead to changes in the conformational behavior of the dendrimer, specifically regarding the average position of the end groups relative to the core. The spatial steric disposition attained with different termini was shown to significantly affect epoxidation reaction activity and selectivity with various alkenes, thus allowing for an original way to control and adjust catalytic behavior under alternating environments.
