  Abstract

전해질 고분자인 polyvinylsulfate(PVS) 및 polystyrenesulfonate(PSS) 존재하에서 나타나는 methylene blue(MB) 및 acridine orange(AO)의 metachromasy현상을 각각 분광학적 방법으로 연구하였다. P/D값의 변화에 따르는 meta-band의 특성적 변화는 stacking이론에 의하여 설명하였으며 PVS-dye계의 stacking효과는 PSS-dye계의 그것보다 더 강하였거 MB가 AO보다 더 강한 stacking효과를 나타냄을 발견하였다. 전에 제안한 바 있는 평면구조의 방향색소들이 수용액속에서 형성하는 dimer의 모형과 dimension을 근거로 고분자사슬 표면에 결합되어 있는 색소분자들의 stacking 모형을 제안하였으며 이 모형을 제안하였으며 이 모형은 여러 연구자들에 의하여 밝혀진 실험적 결과와 비교 검토한 결과 합리적임이 발견되었다. Spectroscopic studies have been carried out on the metachromatic behavior of methylene blue(MB) and acridine orange(AO) in the presence of polyvinylsulfate(PVS) and polystyrenesulfonate(PSS) The characteristic changes of meta-band with the change of P/D value are discussed in terms of stacking theory. It has been found that the stacking effect in the PVS-dye system is stronger than that in the PSS-dye system and that MB shows stronger stacking effect than AO. A stacking model and dimension of bound dyes on the surface of polymer chain is proposed on the basis of the previously suggested model of dimer found in the aqueous solution of planar aromatic dyes. The proposed model is found to be reasonable in accordance with the experimental results obtained by various workers.
