研究了炔基钌基偶氮有机金属化合物的粉末和薄层形式，通过常规的旋涂从溶液中获得。X射线衍射分析表明粉末为部分晶态结构，而相应的薄膜为非晶态。接下来，使膜经受程序化加热和冷却。同时，他们的光学性质进行了监测原位使用光谱椭圆偏振。结果发现，在热处理膜自发地采取了晶体结构，不同于先前观察到的情况下的起始粉末。这种结构取决于特定炔基钌化合物的化学组成。
Alkynyl-ruthenium based azo-organometallics were studied in form of powders and thin layers obtained by conventional spin coating from solution. X-ray diffractometry revealed partly crystalline structure of powders while corresponding films were amorphous. Next, the films were subjected to a programmed heating and cooling. Meanwhile, their optical properties were monitored in situ using spectroscopic ellipsometry. It was found that upon thermic treatment films spontaneously adopted a crystalline structure, different from previously observed in the case of starting powders. This structure depended on chemical composition of a particular alkynyl-ruthenium compound.
