Dependent claims

A polyoxotitanate comprising a metal oxide core and a ligand shell,

wherein the metal oxide core comprises titanium, oxygen and a lanthanide;
wherein the ligand shell comprises one or more light-harvesting ligands coordinated to the lanthanide and one or more bridging ligands;
wherein the one or more light-harvesting ligands comprises one or more of the following classes of compounds:
2-quinolines with a substituent in the 8-position;
quinones;
substituted 2,2′-bipyridines;
substituted 1,10-phenanthrolines;
naphthyridine;
anthraquinones;
catechols;
acetylacetonates (acac);
and a substituted 2,2′;6′,2″-terpyridine;
wherein a bridging ligand is bound to either two Ti atoms of the core or to Ti and a lanthanide of the core via a functional group.
