【摘要】 第一章：简要概述了隐色体染料的分类及性质,详细介绍了两种内酯类染料,即苯酞类和荧烷类染料,及其显色所用的显色剂以及显色机理,并对两种染料的研究进展及应用进行了综述。此外,简单介绍了固相合成法。第二章：采用紫外光谱法对苯酞类隐色体染料3,3-双(2-甲基-1-辛基-1氢-吲哚-3基)苯酞(红色素-16)与几种常见酸和金属离子的显色反应进行了研究,测定了络合物的络合比和不稳定常数,比较其显色效果,并考察了不同表面活性剂、光照及温度对其显色稳定性的影响。结果表明：红色素-16与不同显色剂形成络合物的络合比均为1：1；不同的酸作为显色剂,盐酸的显色效果最好,摩尔吸光系数为1.976×104L·mol-1·cm-1:不同的金属离子作为显色剂时,Al3+和Sn4+显色效果较好,摩尔吸光系数分别为5.500×104和5.780×104L/mol·cm,比盐酸的更大,其中Sn4+与红色素-16的络合物不稳定常数最小,最稳定；阴离子表面活性剂、非离子表面活性剂以及光照对红色素-16的显色有脱色作用,而阳离子表面活性剂和温度对其几乎无影响。第三章：采用紫外光谱法对9’-(2-甲基苯氨基)苯并荧烷(荧烷紫)与几种常见酸和金属离子的显色反应进行了研究,考察了不同表面活性剂对显色体系吸收光谱的影响和并测定了络合物的吸光系数。结果表明：不同酸与荧烷紫显色形成络合物的吸收常数大小依次为：盐酸>硫酸>草酸>邻苯二甲酸>水杨酸,其中盐酸的反应最灵敏；金属离子中A13+和Sn4+的显色效果最好,吸光系数均为1.47×105mL/g·cm；表面活性剂对荧烷紫和盐酸的显色影响与红色素-16相似,阳离子表面活性剂无影响,而非离子型和阴离子型均有不同程度的脱色效果。由此推断,金属离子的显色效果比酸类好,形成的络合物稳定性较高,可作为实际应用中的显色剂。第四章：筛选出色度高且能用水褪色的络合物,采用固相合成法制备了该化合物,并将其应用于白板笔墨水所用色料,通过溶剂、成膜剂、表面活性剂、保湿剂等配方的优化,研制既可干擦又可湿擦的新型白板笔墨水。更多还原

【Abstract】 Chapter1:The classification and the properties of lecuo dyes were briefly introduced. Phthalide dyes and fluoran dyes were described in details, including the developers and the mechanism of chromogenic reaction. The research progress and applications of two lactone dyes were reviewed. Moreover, the method of solid-phase synthesis was recommended.Chapter2:The chromogenic reaction between3,3-bis(dimethyl-l-octyl-1H-indolyl-3-yl) phthalide (red-16) and some acids and metal ions were investigated by UV-Vis spectrometry. The absorption spectra of chromogenic system, the complexation ratio and dissociation constant of the complexes formed by red-16and developers were studied in details. And the effects of different surfactants, lights and temperature on the chromogenic reaction were were investigated. The results showed that the complexation ratios of the complexes were all1:1.When acids act as developers, hydrochloric acid was a good developer because that the molar absorptivity of the complex was1.976×104L·mol-1·cm-1. While Al3+and Sn4+were superior to hydrochloric acid. Anionic surfactants and nonionic surfactants made the system decolored, while cationic surfactants did not. And different temperature had no decoloration effect on the chromogenic system too. The dissociation constant the complex formed by red-16and Sn4+was small. It was indicated that the complex was more stable.Chapter3:The chromogenic reaction between9’-(2-methylphenylamino) benzofluran(purple fluroan) and some acids and metal ions were investigated by UV-Vis spectrometry. The absorption spectra of chromogenic system, absorption coefficient of the complexes formed by fluroan purple and developers were studied in details. And the effects of different surfactants on the chromogenic reaction were also investigated. The results showed that absorption coefficients of the complexes formed by purple fluroan and acids reduced by following order:αD. hydrochloric acid>αD-sulfuric acid>αD-oxalic acid>αD-phthalic acid>αD-salicylic acid (D stands for purple fluroan). Anionic surfactants and nonionic surfactants made the system decolor, while cationic surfactants did not. When metal ions act as developers, Al3+and Sn4+were superior to Fe3+And absorption coefficients of the complexes were all1.47×105mL/g·cm. It was concluded that metal ions are more suit for developers than acids in practical application.Chapter4:The complex which had high colourity and could be decolored by water was selected. Than it was synthesised by solid-phase method and used as the pigment of ink of white board marker. The ink which can be wiped by both water and rag was prepared using uniform and orthogonal experiment method.更多还原
