Rational design of carborane-based Cu2-paddle wheel coordination polymers for increased hydrolytic stability

A new unsymmetric carborane-based dicarboxylic linker provided a 1D Cu-2-paddle wheel coordination polymer (2) with much higher hydrolytic stability than the corresponding 2D Cu-2-paddle wheel polymer (1), obtained from a related more symmetrical carborane-based linker. Both 1 and 2 were used as efficient heterogeneous catalysts for a model aza-Michael reaction but only 2 can be reused several times without significant degradation in catalytic activity.

Automated summary

This study identified a new unsymmetric carborane-based dicarboxylic linker that produced a coordination polymer with higher hydrolytic stability. The polymer obtained from this new linker showed higher catalytic efficiency in model reactions and could be reused multiple times without significant degradation in catalytic activity as compared to a polymer from a more symmetrical carborane-based linker.
