Multiple intramolecular motions consume the excited-state energy of luminogenic molecules upon photoexcitation and lower the emission efficiency.The low frequency rotational motion of aromatic rings can be facilely restricted by steric constraint in the condensed phase,but the high frequency bond stretching motion can hardly be suppressed by aggregation.
