Heck coupling 반응을 이용해서 poly{2-[2-(2,5-bis-dodecyloxy-4-propenyl-phenyl)-vinyl]-
7-methyl-fluoren-9-one(PFone), poly{2-[2-(2,5-bis-dodecyloxy-4-propenyl-phenyl)-vinyl]-7-methyl-fluoren-9-ylidene}-malonitrile(PF2CN)을 합성하였다. 합성한 중합체의 광학적, 전기화학적 특성을 흡수, 형광분광법 및 cyclic voltammetry(CV)를 통해 확인하였다. PFone과 PF2CN 필름의 흡수 극대치는 410 nm과 410.5 nm에서 나타났다. PFone 및 PF2CN의 최대 발광파장은 각각 633과 635nm로 나타났다. PFone과 PF2CN의 band gap은 각각 2.06eV 과 2.36eV이고 CV를 통해 측정한 LUMO 에너지 준위는 -3.36eV 와 -3.46eV로 나타났다.
Poly{2-[2-(2,5-bis-dodecyloxy-4-propenyl-phenyl)-vinyl]-7-methyl-fluoren-9-one (PFone)
and poly{2-[2-(2,5-bis-dodecyloxy-4-propenyl-phenyl)-vinyl]-7-methyl-fluoren-9-ylidene}-malonitrile (PF2CN) were synthesized by the Heck coupling reaction. Optical and elctrochemical properties of polymers were investigated by the UV-Vis spectrophotometry, fluorometry and cyclic voltammetry. The absorption maximum wavelength of PFone and PF2CN appeared at 410 nm and 410.5 nm, respectively. The photoluminescence maximum wavelength of PFone and PF2CN showed at 633 nm and 635 nm. The band gap energy of PFone and PF2CN figured out from the UV-Vis spectra were 2.06 eV and 2.36 eV, respectively. The LUMO energy level of PFone and PF2CN estimated from the cyclic voltammetry were -3.36eV and -3.46eV, respectively.
