Fe(III)-doped coordination polymer of Mn13-clusters with improved activity for oxygen reduction reaction
(2019)Fe(III) dopants have been introduced into a porous coordination polymer of Mn13-clusters to form composite materials. The resulting Fe@Mn13-polymer showed enhanced oxygen reduction reaction (ORR) activity, making it a ... -
Self-assembled bright luminescent hierarchical materials from a tripodal benzoate antenna and heptadentate Eu(III) and Tb(III) cyclen complexes
(2018)The europium heptadentate coordinatively unsaturated (Eu(III)) and the terbium (Tb(III)) 1,4,7,10-tetraazacyclododecane (cyclen) complexes 1 and 2 were used in conjunction with ligand 3 (1,3,5-benzene-trisethynylbenzoate) ... -
A Mn13-cluster based coordination polymer as a co-catalyst of CdS for enhanced visible-light driven H 2 evolution
(2018)A coordination cluster-based polymer was used for the first time as a noble-metal-free co-catalyst of CdS, giving rise to significantly enhanced photocatalytic H2 production. This work demonstrates the feasibility of cluster ... -
