光敏热显成像材料显影过程含银中间体的合成与表征

Synthesis and Characterization of Silver-Intermediates in the Development Process of Photothermographic Material

光敏热显成像(photothermographic material,简称PTG)材料是近十多年来国际感光界关注的热点。采用液相沉淀法合成了PTG材料热显成像过程的含银中间体邻苯二甲酸二银(Ag2PA),并进一步使其与酞嗪(PHZ)络合形成了Ag2PHZ2PA.H2O配合物,通过元素分析、电感耦合等离子体原子发射光谱分析(ICP-AES)对Ag2PA与Ag2PHZ2PA.H2O配合物的元素组成进行了确定,采用X射线粉末衍射分析(XRD)、傅里叶变换红外光谱分析(FTIR)以及热分析(TG与DSC)等方法对Ag2PA与Ag2PHZ2PA.H2O进行了表征,实现了对PTG材料热显成像过程含银中间体的定性分析。

Photothermographic material （PTG） is one of the frontier subjects in the field of photographic science during the last decade. In the present paper, the silver-intermediate in development process of PTG material-disilver phthalate （Ag2PA） was prepared by the liquid deposition method, and Ag2PHZ2PA · H2O complex was synthesized successfully by liquid dispersion means using Ag2PA and phthalazine （PHZ） as the reactants. The composition of Ag2PA and Ag2PHZ2PA · H2O was determined by ICP-AES and elemental analysis, and the two silver-intermediates were characterized with XRD, FTIR, TG and DSC. As a result, the silver-intermediates in the development process of PTG material, Ag2PA and Ag2PHZ2PA · H2O, were qualitatively analyzed respectively.
