azo compound 偶氮化合物。

azo dyes

The composites not only show excellent photo - responsive properties in the visible and near - ir region ( 450 ~ 850 nm ) , but also show complementary and synergetic enhancement effects in photosensitivity in the visible and near - ir region . the reasons for the enhanced photoconductive properties and new effects are explained in terms of the partial and directional charge transfer from phthalocyanine to azo compound in these azo / tiopc composites . 2 研究發現這兩種復合材料體系在可見光區和近紅外光區( 450 850nm )均有光譜響應,光譜響應范圍得到了拓寬,并在該波長范圍內都有優良的光電導性能,呈現出明顯的光電導性能協同增強和互補效應,該復合材料體系中酞菁向偶氮發生的部分定向的電荷轉移是光電導性能協同增強和互補效應產生的物理起因。

A review with 44 references is given on recent development of heterocyclic azo compounds ' application in spectrophotometric analysis of copper , zinc , and iron in biological sample including three kinds of heterocyclic azo compounds : pyridylazo compound , imidazolylazo compound , and triazolylazo compound 摘要綜述了近年來應用偶氮類顯色劑測定生物樣品中銅、鋅、鐵的光度分析發展狀況,從吡啶偶氮類試劑、咪唑偶氮類試劑以及三氮唑偶氮類試劑加以歸納,引用文獻44篇。
