Lighting the way

Light emitting diodes provide an efficient form of lighting while solar cells give us energy from sunlight. Thienyl carboxylates attached to MM quadruple bonds have shown interesting photophysical properties with potential applications in these areas. Malcolm Chisholm et al. discuss in their Hot Article the electronic properties of four new compounds which are based on Mo and W complexes bound to 5 membered heterocycles containing either O or Se.

The authors thoroughly characterize the complexes, computationally calculate the electronic structures, examine the electronic absorption spectra and steady state emission spectra, use transient absorption spectroscopy and electrochemical studies. The results are very interesting and indicate these complexes may have potential in solar cells given their different electronic states.
