\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), split into parallel and perpendicular polarisation directions with a polarising beam splitter (BS), (DM)  and recorded with two detectors D$_\parallel$ and D$_\perp$. detector (D).  The anisotropy (c) was calculated from the fluorescence time decays in parallel and perpendicular polarisation directions  (b) with eq~\ref{eq:anisotropy}, and fitted with an exponential function (eq~\ref{eq:2expfit}).
