Site-dependent hole filling of satellite holes has been studied by the excitation of 9-amino-6-chloro-2-methoxyacridine to fill the primary zero-phonon hole and satellite holes of 4,4-difluoro-5-(2-thienyl)-4-bora-3a,4a-diaza-s-indacene-3-propionic acid, succinimidyl ester. The results show that intermolecular energy transfer can trigger the filling of the primary holes. More important, two different filling rates are observed for four different satellite holes. The filling rate is more rapid on the red side than on the blue side of the absorption band.
