Self-assembled zinc(II) Schiff base polymers for applications in polymer light-emitting devices.
Thermally stable zinc(II) Schiff base polymers (decomposition temperature up to 461 degrees C; M(n)= 13580 to 20440) formed by self-assembly reactions of zinc(II) salts and salicylaldimine monomers exhibit blue to yellow PL with quantum yields up to 0.34 in DMF; PLEDs employing these polymers as emitters give green or orange EL with turn-on voltage at 5 and 6 V and maximum efficiency of 2.0 and 2.6 cd A(-1) respectively.
