## Results of measurements of the kinetics of thermally driven reactions in polycrystalline samples of a photochromic dihydropyridine derivative, 4,4-(biphenyl-2,2 H -diyl)-2,6-diphenyl-1-methyl-1,4-dihydropyridine (BDH), are presented. The measurements have been carried out using the differential
Reactions of 2,2 0 -biindanylidene-1,1 0 ,3,3 0 -tetraone with arylmagnesium bromide gave 3,3 0 -diaryl-3,3 0 -dihydroxy biindenylidenedione derivatives. These compounds exhibited photochromism in solid state, in which the formation of the isomeric radical species was confirmed by the election spin
