New indenopyrazine derivative of 6,6,12,12-tetrahexyl-2,8-di-thiophen-2-yl-6,12-dihydro-diindeno [1,2-b;1',2'-e]pyrazine (m-thio-HPY) and new indenopyrazine polymer of poly (6,6,12,12-tetrahexyl-2,8-di-thiophen-2-yl-6,12-dihydro-diindeno [1,2-b;1',2'-e]pyrazine) (poly(m-thio-HPY)) were synthesized based on suzuki coupling reaction and Yamamoto polymerization. Optical and electronic properties were examined by UV-Vis. absorption spectrum, PL spectrum, and cyclic voltammetry. PL maximum values of synthesized compounds are 524 and 590 nm (m-thio-HPY) and 529 and 563 nm (Poly(m-thio-HPY)) in film state. Poly(m-thio-HPY) as an emitting material was tested in organic light emitting diodes (OLEDs). The device showed 0.38cd/A of luminance efficiency and CIE value of (0.39, 0.59). |
