Abstract
Three different alkyl-end phenantroimidazole modified benzotriazole based conjugated polymers were synthesized. Optical and electronic properties of the conjugated polymers were investigated. Optical/ electronic band gaps of polymers were found as 2.62/ 3.02, 2.22/ 2.39, and 1.89/ 2.01 eV for P1, P2, and P3, respectively. Polymers revealed multichromic properties and fast switching times with reasonable contrasts for P1 (1950 nm, 49% transmittance, 0.2 s) and P2 (1500 nm, 61%, 0.4 s). Strong interaction between phenantroimidazole and conjugated polymer backbone inhibited the photoluminescence of phenanthroimidazole except in thin film for P3. However, electroluminescence did not show emission for phenanthroimidazole unit. P1 incorporated electroluminescent device exhibited superior performance. The highest luminance efficiency for P1 based device was 3.01 cd/A at 9.5 V at a luminance value of 1665 cd/m2.
