K. Katsuma et Y. Shirota, A NOVEL CLASS OF PI-ELECTRON DENDRIMERS FOR THERMALLY AND MORPHOLOGICALLY STABLE AMORPHOUS MOLECULAR MATERIALS, Advanced materials, 10(3), 1998, pp. 223
Communication: Functional materials for organic light-emitting diodes
(LEDs), in addition to exhibiting the qualities listed in the previous
article, should also be thermally and morphologically stable and not
crystallize even above the glass transition temperature. The synthesis
and properties of hyperbranched pi-electron systems (such as that in
the Figure) fulfilling these condition are presented, together with th
eir unique multiredox properties.
