DOI: 10.1021/acs.jafc.9b00164
Abstract: Considerable interest in using lanthanide complexes in optics have been well-known persisted for a long time. But such molecular-based edifices have been excluded from practical application because of their poor thermal or photo stabilities. Here… read more here.
