Ultrafine Gold Clusters Incorporated into a Metal–Organic Framework

Trapping gold! A novel porous metal–organic framework (MOF) with an unprecedented hexagonal (4,8)-connected topology has been assembled and characterized. By employing the resultant MOF as a host, for the first time, ultrafine Au clusters with an average atom number of 2.5 were successfully prepared and incorporated into the pores of the MOF through a simple surfactant-free method (see graphic).
