  Abstract

고분자전해질인 Chondroitin sulfate A(CSA) 및 Chondroitin sulfate C(CSC) 존재하에서의 methylene blue(MB) 및 acridine orange(AO)의 metachromasy 현상에 관하여 각각 분광학적 방법으로 연구하였다. P/D값의 변화에 따르는 meta-band의 특성적 변화를 stacking 이론에 의하여 설명하였으며, staking 효과의 정량적 고찰에 의하여 고분자의 반복단위당 결합하는 색소분자의 수를 계산한 결과 MB가 AO보다 강한 stacking 효과를 나타냄이 발견되었다. CAS의 안정한 형태의 골격구조와 dimension을 발견하고 평면 방향색소의 free dimer의 모형을 근거로 CSA의 골격표면에 결합한 색소분자의 stacking모형과 dimension을 제안하였다. Spectroscopic studies have been carried out on the metachromatic behavior of methylene blue(MB) and acridine orange(AO) in the presence of chondroitin sulfate A(CSA) and chondroitin sulfate C(CSC). The characteristic changes of the meta-band with the changes of P/D value are discussed in terms of the stacking theory. Quantitative studies on the stacking effect are made to calculate the number of bound molecules of dye per unit molecule of the polyanion. The result shows that MB has stronger stacking effect than AO. A stacking model and the dimension of the bound dyes on the surface of the polyanion are proposed, on the basis of the dimer model of planar aromatic dyes and the most stable conformation of the CSA chain. The model is found to be reasonable in accordance with the experimental results.
