A series of poly(2-alkoxy-1,4-phenylenevinylene)'s was synthesized by processible precursor method. In this thesis, three poly(p-phenylenevinylene) (PPV) derivatives were included, poly(2-methoxy-1,4-phenylenevinylene) (PMPV), poly(2-butoxy-1,4-phenylenevinylene) (PBPV) and poly(2-dodecyloxy-1,4-phenylenevinylene). These polymers were characterized using UV-Visible-NIR, FT-IR spectroscopy and DSC, TGA thermal analyzer. The third order nonlinear optical susceptibilities of the polymers were determined using third harmonic generation (THG) method at 1907 nm. Measured third order NLO coefficients are $10^{-11}~10^{-12}$ esu order and as the side chain length is increased, the third order NLO coefficient is decreased because of the side chain effect on conjugation and of volume fraction. The conductivities of the polymers were measured by four-probe method. These polymers were doped with both $FeCl_3$ and $I_2$, and the maximum conductivities ranged between $10^0$ and $10^{-1}$ S/cm. The conductivity is decreased, as the side chain length is increased. Photoluminescence spectra of the polymers were obtained in the search for new materials for light emitting devices. The emitting wavelength range of these materials is from 530 nm to 630 nm(yellow-red color).
비대칭적으로 치환된 폴리 (2-메톡시 -1,4-페닐렌비닐렌), 폴리 (2-부톡시 -1,4-페닐렌비닐렌)과 폴리 (2-도데실옥시-1,4-페닐렌비닐렌)을 선중합체를 거쳐 합성하였다. 3차 조합파 방법으로 3차 비선형 광학계수를 측정하였다. 측정된 3차비선형 광학계수는 PMPV인 경우 $1.2\times10^{-11}$ esu, PBPV인 경우 $5.8\times10^{-12}$ esu이고, PDPV인 경우 $2.5\times10^{-12}$ esu이였다. $\chi^{(3)}$값은 곁가지가 길어질수록 감소하였다. 이것은 띠 에너지의 차이와 곁가지 부피의 영향으로 설명할 수있다. PMPV, PBPV와 PDPV의 전도도를 $FeCl_3$와 $I_2$도 핑하에서 측정하였다. 연신시키지 않은 것은 $10^{-4}\sim10^{-2}S/cm$ 값을, 연신시킨 것을 $10^{-3}\sim10^{-1}S/cm$의 값을 보였다. 곁가지 알콕시기의 길이가 길수록 전기전도도 값들은 감소하는 경향을 보였다. PMPV, PBPV와 PDPV의 광발광 스펙트럼을 발광 다이오드로써의 물성을 알아보기 위해 얻었다. 380nm의 빛으로 여기시켰을 때, PMPV, PBPV과 PDPV는 530nm~630nm에서 발광을 보였으며, 그 색은 주황색이었다.
