要旨:
Three cocrystals of the light-stable compound 1,1,6,6-tetraphenyl-2,4-hexadiyne-1,6-diol (I) with light-sensitive molecules 1,2-dimethyl-2(1H)-pyridinone (a), 6-methyl-2(1H)-pyridinone (b), and 2-methyl-2(1H)-pyridinone (c) were exposed to UV light. The light-sensitive molecules undergo molecular flip. The estimated activation energy of the flip is 9.72 kJ/mol. The kinetics of the reaction of I-c was studied showing sigmoidal behavior with Avrami exponent of n = 0.95(6), suggesting homogeneous reaction.
