초록
본 연구에서는 단량체로 diphenylacetylene 유도체(DPAmC18)를, 가교제로 2관능성 1,4-bis[phenylethynyl]benzene(PEB)를 사용하여, 신축성을 가지는 형광 공액고분자를 합성하였고 물성을 평가하였다. FTIR 분석을 통해 생성고분자들의 구성비를 확인하였으며, XRD, DSC, 자외가시흡광 및 형광방출 스펙트럼 분석을 통해 열역학적/구조적/광학적 특성을 비교 평가하였다. 고분자 내 PEB 함유량의 증가에 따라 단일중합체인 PDPAmC18의 열역학적, 구조적 특성이 점차적으로 변한 반면, 형광특성의 변화는 거의 없었다. 상온에서 UTM을 이용한 기계적 물성을 측정한 결과, PEB의 함유량이 10%인 중합체는 70%~100%의 인장변형 범위에서 가장 가역적인 신축성을 보임과 동시에 가역적인 형광 및 편광형광 변화를 나타내었다. 이 결과는 이들 고분자의 형광장력센서로서의 응용가능성을 시사한다.
Stretchable fluorescent conjugated polymers were synthesized by copolymerization of diphenylacetylene derivative (DPAmC18) and di-functional 1,4-bis[phenylethynyl]benzene (PEB) using as a monomer and a cross-linker, respectively, in different feed ratios and their properties were investigated. The compositional ratios of the polymers were confirmed by FTIR spectroscopy and their thermodynamic/structural/optical properties were evaluated and compared by XRD, DSC, UV-vis absorption and fluorescence (FL) emission spectroscopic analyses. The thermodynamic/structural feature of the homopolymer, PDPAmC18, varied gradually according to the amount of PEB in the polymers while the FL emission was almost not changed. As a result of UTM measurement at room temperature, the polymer having a 10% feed ratio of PEB showed the most reversible stretchability in a tensile strain range from 70% to 100% and, simultaneously, the FL and polarized FL emission were changed reversibly. These results suggest a potential application of our polymers using as a FL tension sensor.
