\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 detector (D). The anisotropy (c) was calculated from a PMT. (b) Schematic of  the fluorescencetime  decays in parallel and perpendicular polarisation directions (b) with eq~\ref{eq:anisotropy}, and fitted directions, from which the anisotropy (c) was calculated  with an exponential function (eq~\ref{eq:2expfit}). eq~\ref{eq:anisotropy}.
