Interaction of the triplet biradical, 1,1′-biacenaphthene-2,2′-diyl (BR) with dibromomethane has been examined by means of transient absorption measurements and kinetic analysis. The absorption spectrum of BR in CH<SUB>2</SUB>Br<SUB>2</SUB> shows a red shift compared with those in other solvents with various polarities. The spectral result indicates that the red shift is not due to effect of solvent polarity but due to existence of weak electronic interaction acting directly between BR and CH<SUB>2</SUB>Br<SUB>2</SUB>. The nonlinear dependence of decay rates of BR upon [CH<SUB>2</SUB>Br<SUB>2</SUB>] is interpreted in terms of a simple kinetic model of solvation based on solvent replacement between cage and bulk.
