Grafting of a gold complex to an organo-polyoxometalate delivers catalytically active bitopic hybrids. The gold end activates allenes, while the metal-oxide surface can capture protons (see scheme). The scope of the gold-catalyzed oxacyclization of allenols is expanded to highly sensitive tertiary benzylic alcohols.

Organophosphate nerve agents (OPs) are widely used as pesticides and chemical agents and pose a threat to human health and life. At present, most personal protective equipment usually only serves as physical protection and does not have an effect of chemical detoxification. In this work, ultra lightweight graphene oxide aerogels (GAs) have been used as a multifunctional skeleton to integrate the metal-organic frameworks (MOFs) and molecularly imprinted polymers (MIPs) together for obtaining a high-performance hybrid material (MOFs/MIPs@GAs) on hydrolysis detoxification of OPs.
