溶胶－凝胶法制备酞菁染料掺杂ormosil研究

STUDY ON PREPARATION AND PROPERTY OF PHTHALOCYANINE-DOPED ORMOSIL BULK

用溶胶－凝胶法制备了酞菁染料掺杂ｏｒｍｏｓｉｌ材料．研究发现，硅醇盐－水－乙醇－酞菁染料－有机溶剂体系中，乙醇、水的加入量和有机溶剂的选择对制备出均匀掺杂的ｏｒｍｏｓｉｌ块体至为重要．加入较少量的水和适量的乙醇，采用回流工艺加速水解过程，选用溶解酞菁能力强、沸点高的有机溶剂可以制备出均匀的ｏｒｍｏｓｉｌ块体．分散在ｏｒｍｏｓｉｌ中，田菁染料显示出不同于其在液体中的光谱性质．

Phthalocyanine-doped ormosil bulks prepared by sol-gel process were obtained.Content of H_2O, C_2H_5OH, refluxing and property of organic .solvent used to preparegood phthalocyanine-doped ormosil bulks, phthalocyanine doped in ormosil showed absorption spectra different from that in organic solvent. The cages in ormosil may haveslightly polar nature and one molecule or several molecules size.
