The first example of a homoleptic f-block borolide sandwich complex is presented and shown to be a high-performance single-molecule magnet (SMM). The bis(borolide) complex [K(2.2.2)][[1-(piperidino)-2,3,4,5-tetraphenylborolyl]2Dy] (1) features an unu

Lanthanides (LnIII) are well known for their characteristic emission in the near-infrared region (NIR). However, direct excitation of lanthanides is not feasible as described by Laporte's parity selection rule. Here, we obtain NIR emission from [L–

The metal-ion-complexing properties of the tetradentate ligand 2,2'-bi-1,10-phenanthroline (BIPHEN) in 50% CH3OH/H2O are reported for a variety of metal ions. BIPHEN (with two reinforcing benzo groups in the backbone) was compared to other tetrapyrid
