The paper presents a series of novel water-soluble derivatives of Rosebengal. Solubility in water of the C-2 Rose bengel esters has been obtained by the attachment of the proper water-soluble moiety to the dye molecule. It is shown that size of the attached molecule has a significiant influence on the spectroscopic properties of the derivatives. The long side chain strongly influences on the position
本文提出了一系列新型的孟加拉玫瑰水溶性衍生物。通过将适当的水溶性部分连接到染料分子上,可以获得C-2 Rose Bengel酯在水中的溶解度。结果表明,连接分子的大小对衍生物的光谱性质有重要影响。长侧链强烈影响吸收λmax和发射光谱的位置。侧链为附着的分子创造了微环境。这使得H 3的扩散更加困难OXXX离子进入染料分子,并导致x吨残基的酚基质子化的pK值明显降低。这些类型的衍生物即使在低pH值下也可以在水中进行光氧化。
