The solvate of a layer witn a limiting content of benzene and solvate with residual content of benzene were synthesized. This synthesis was conducted by means saturation with liquid benzene of the layer of active carbon with grafted ethanolamine PVC derivatives that are sewn to cellulose tissue and following evaporation to an undesorbable amount. It was established that the spectrum with a limited benzene content shows a change in the number and position of the bands as well as an increase in quantum yield. In saturated solvate bands are blured into one wide band and luminescence extinction by approximately 75%. It is shown that the first case of wall solvation corresponds to the formation of host-guest complexes between cycles of ethanolamine derivatives of PVC and benzene molecules, as well as charge transfer complexes between aromatic wall structures and benzene molecules. In the second case, the limiting filling of the pores led to a stuctural deformation of the flat sections of the pores in the coal, which led to dilution of the bands and luminescence extinction.
