PAQ(poly-2-[2-(2,5-Bis-dodecyloxy-4-vinyl-phenyl)-vinyl]-anthraquinone)과 PAN4CN(poly-
2-{2-[2-(2,5-Bis-dodecyloxy-4-vinyl-phenyl)vinyl]-10-dicyanomethylene-10H-anthracen-9-ylidene}-malononitrile)을 Heck coupling reaction을 이용하여 합성하였다. 합성한 중합체의 전기적, 광학적 특성은 UV-visible spectra, photoluminescence (PL) spectra 및 cyclic voltammetry 측정을 통해 확인하였다. 흡수 스펙트라 측정 결과, thin film에서의 흡수극대치는 PAQ 와 PAN4CN은 334nm에서 나타났고, 용액에서는 PAQ 338nm, PAN4CN은 336nm 나타났다. 발광 극대치의 측정결과 PAQ는 thin film에서 420nm와 용액상에서는 416nm, PAN4CN은 thin film에서 395nm와 용액에서는 550nm로 각각 나타났다. PAQ과 PAN4CN의 band gap은 각각 2.16 eV, 2.04 eV이고 CV를 통해 LUMO 준위는 -3.64eV, -3.52eV로 나타났다.
We synthesized PAQ(poly-2-[2-(2,5-Bis-dodecyloxy-4-vinyl-phenyl)-vinyl]-anthraquinone),
PAN4CN(poly-2-{2-[2-(2,5-Bis-dodecyloxy-4-vinyl-phenyl)-vinyl]-10-dicyanomethylene-10H-anthracen-9-ylidene}-malononitrile) as Hack coupling reaction. Electrical and optical properties of polymers were investigated by UV-vis spectra, photoluminescence (PL) spectra and cyclic
voltammetry. The maximum wavelength of PAQ and PAN4CN film showed at 334nm. In case of
PAQ and PAN4CN film , the maximum of photoluminescence(PL) appeared at 420nm and 416nm,
respectively. PAN4CN, the maximum PL of PAN4CN film and solution showed at 395nm and 550nm, respectively. The band gap of PAQ and PAN4CN were 2.16eV, 2.04eV respectively. In addition, The LUMO energy level figured out from the cyclic voltammetry were -3.64eV, -3.52eV respectively.
