Dodecyloxy-substituted stilbenoid dendrimers

Photochemistry and mobility of the stilbenoid dendrimers [all-( )-l,3,5-tris[2-(3,4,5-tridodecyloxyphenyl)ethenyl]benzene] and [all-( )-l,3,5-tris(2- 3,5-bis[2-(3,4,5-trido-decyloxyphenyl)ethenyl]phenyl ethenyl)benzene] in their neat phases were synthesized and investigated [129]. Selectively deuterated, dodecyloxy-substituted stilbenoid dendrimers of the first and second generations (Figure 1.21) were synthesized by a convergent synthesis, using the Wittig-Homer reaction. Molecules deuterated at the... 

Photochemistry and mobility of stilbenoid dendrimers in their neat phases have been studied [36]. The photochemistry and the fluorescence in different crystal and liquid crystal phases selectively containing deuterated, dodecyloxy-substituted stilbenoid dendrimers of the first and second generations were investigated. Molecules deuterated at the a-position of the alkoxy chains were involved in reactions of double bonds in the liquid crystal phases whereas no photoreactions occurred in the crystal...
