Abstract

AG acknowledges a postgraduate fellowship by the EPSRC funded doctoral training centre 'integrated magnetic resonance'. BEB is grateful for an EaStCHEM Hirst Academic Fellowship by the School of Chemistry, St Andrews, and funding from the People Programme (Marie Curie Actions) of the European Union's Seventh Framework Programme (REA 334496). ; Pulsed electron paramagnetic resonance (EPR) spectroscopy is gaining increasing importance as a complementary biophysical technique in structural biology. Here, we describe the synthesis, optimisation, and EPR titration studies of a spin-labelled terpyridine Zn(II) complex serving as a small-molecule model system for tuneable dimerisation. ; Publisher PDF ; Peer reviewed
