Abstract
We prepared coordination networks that show relatively strong emission with through-space charge-transfer (TSCT) transitions. Thermolysis of a kinetically assembled network with Cu2Br2 dimer connectors, which was assembled from a CuBr cluster and the Td ligand 4-4-tetrapyridyltetraphenylmethane (4-TPPM), generated a highly luminescent network composed of Cu+ connectors and 4-TPPM linkers with CuBr2– guests. We clarified that the electronic transitions in this network include TSCT in addition to the typical metal–ligand charge transfer (MLCT) observed in conventional Cu complexes.
