All Rights Reserved. Novel Self-Assembled Metallo-Homopolymers and Metallo-alt-copolymer Containing Terpyridyl Zinc(II) Moieties. Chen, Yi-Yu; Tao, Yu-Tai; Lin, Hong-Cheu (Department of Materials Science and Engineering, National Chiao Tung University, Hsinchu, Taiwan). Macromolecules, 39(25), 8559-8566 (English) 2006 American Chemical Society. CODEN: MAMOBX. ISSN: 0024-9297. DOCUMENT TYPE: Journal CA Section: 78 (Inorganic Chemicals and Reactions) Section cross-reference(s): 72, 73 Novel terpyridyl Zn(II)-based metallo-homopolymers I [R = CH2(CH2)4Me, CH2(CH2)4CH2R (R = N-carbazolyl)], and a metallo-alt-copolymer with alternation of the same two linkers, contg. carbazole pendants attached to the C-9 position of fluorene by long alkyl spacers, were constructed by self-assembled reaction. The integrated ratios of 1H NMR reveal a facile result to distinguish the differences between metallo-homopolymers and copolymers. To further study these polymers, UV-visible and PL spectral titrn. expts. 115-19-5 and 189367-54-2 which are cas registry numbers are also used here. were also carried out by varying the molar ratios of Zn(II) ions to monomers. The photophys. properties of these polymers exhibited blue PL emissions (around 420 nm) with quantum yields of 11-23% (in DMF) and the PL results revealed that the formation of excimers were suppressed by the incorporation of carbazole pendant groups. The EL results showed green EL emissions (around 550 nm) with turn-on voltages of 6.0-6.5 V, max. efficiencies of 0.85-1.1 cd A-1 (at 100 mA cm-2), and max. luminances of 1704-2819 cd/m2 (around 15 V), correspondingly. .
