In this context, the accumulation of active Ru centers in macrocyclic arrays or coordination oligomers and polymers has proven to be very beneficial for an enhanced stability under operating conditions and to facilitate surface adhesion in heterogeneous systems. For a better insight into structure\u2013activity relationships though, well\u2013defined systems with a precise control over stoichiometry and constitution are highly desired.
