On the other hand, a decrease in rotational freedom of the oUgophenyl system was expected to enhance the optical properties, especially the fluorescence quantum yield in neat films and also the morphologic stability. This led to the development of the starburst-spiro-oligophenyles 30-32 [73]. Moreover, the terminal fluorene units in these compounds act as spacers, which prevent interaction between the main chains in the solid state. In the case of... [Pg.101]
