説明

<jats:title>Abstract</jats:title><jats:p>Four alternating arylamino‐functionalized copolymers were synthesized in a Suzuki copolymerization applying 4, 4′‐(2,7‐dibromo‐9<jats:italic>H</jats:italic>‐fluorene‐9,9‐diyl)dianiline, 4,4′‐(2,7‐dibromo‐9<jats:italic>H</jats:italic>‐fluorene‐9,9‐diyl)<jats:italic>bis</jats:italic>(<jats:italic>N,N</jats:italic>‐diphenylaniline), 4‐(3,6‐dibromo‐9<jats:italic>H</jats:italic>‐ carbazol‐9‐yl)aniline and 4‐(3,6‐dibromo‐9<jats:italic>H</jats:italic>‐carbazol‐9‐yl)‐<jats:italic>N,N</jats:italic>‐diphenylaniline in combination with 2,2′‐(9,9‐dioctyl‐9<jats:italic>H</jats:italic>‐fluorene‐2,7‐diyl)<jats:italic>bis</jats:italic>(1,3,2‐dioxaborinane). The resulting novel alternating copolymers were fully characterized. The copolymers revealed blue light emission and wide optical bandgaps of at least 2.93 eV for the fluorene‐based and 3.07 eV for the carbazole‐based polymers. The amino‐functions allow to tie semiconducting CdTe nanocrystals (NCs) and to synthesize a series of composites with CdTe NCs. Moreover, tuning the emission color over a wide range by tying these CdTe NCs results in a facile preparation of organic–inorganic semiconductor composites with emission colors “à la carte.” © 2010 Wiley Periodicals, Inc.
