\label{fig:setup} Schematic diagram of the anisotropy measurements. (a) Simplified diagram of the experimental setup. The sample solution was placed on a confocal microscope stage and excited with a polarised, pulsed laser. The fluorescence from the sample was reflected from a dichroic mirror (DM) and recorded with a PMT. hybrid photodetector (HPD).  (b) Schematic of the fluorescence decays in parallel and perpendicular polarisation directions, from which the anisotropy (c) was calculated with eq~\ref{eq:anisotropy}.
