A tripodal podand has been prepared and complexed to ruthenium(II) creating a metal complex with C3-symmetry and an enclosed cavity. The complex shows the anticipated enhanced emission when compared to [Ru(bipy)3]2+ in acetonitrile. The emission from

The potential of IR absorption and Raman spectroscopy for rapid identification of novel psychoactive substances (NPS) has been tested using a set of 221 unsorted seized samples suspected of containing NPS. Both IR and Raman spectra showed large varia

In this perspective, we highlight the issue of meridional (mer) and facial (fac) orientation of asymmetrical diimines in tris-chelate transition metal complexes. Diimine ligands have long been the workhorse of coordination chemistry, and whilst there
