An experimental study on the pumping-power dependence of photogrowth and decay properties of the long-lived midgap absorption band in an MX chain compound [Pt(en)2][Pt(en)2Cl2](BF4) 4, (en) =ethylenediamine, is reported. The data show that the upper bound of the density of solitonic photogenerated states is determined by autophotobleaching processes. The observed whole course of the photogrowth and decay can be described well on the basis of a lattice ring model, in which intersite energy barriers serve as the particle source as well as barriers against hopping motion.
