Abstract

The photochemical behavior of a new photochromic liquid crystalline (LC) carbosilane dendrimer of the second generation (D2) in CHCl₃ and THF was described. Thirty-six 4-butoxyazobenzene mesogenic fragments were attached in its periphery. The intensity of light, intensity of absorption light, molar extinction coefficient, maximum absorption wave length, quantum yield, activation energy, reaction rate constant of trans/cis photochemical isomerization, photochemical back-isomerization, thermal back-isomerization and the equilibrium constant of photochemical back-isomerization reaction were discussed.

Key words: photochromic liquid crystalline dendrimer, photo-electro information functional material, trans/cis photoisomerization, photo chemical back-isomerization, trans/cis isomer ratio, thermal back-isomerization, activation energy
