在本工作中，我们用光电子能谱和X射线吸收光谱研究了(t-Bu)(4)PcMg(四叔丁基酞菁镁)在多晶金和单晶金衬底上的电子结构和分子取向，并与未取代的PcCu(铜酞菁)进行了比较。C1S光电子能谱描述类似于未取代的亲属，只是增加了脂肪族取代基组分。激发能的变化导致了C1S谱形状的明显不同，这对于分析最上层的分子取向是非常有用的。结果表明，尽管(t-Bu)(4)PcMg具有空间要求高的取代基，但(t-Bu)(4)PcMg的有序升华膜是可获得的，但分子的取向与未取代亲属的取向不同。
In this work we have investigated the electronic structure and the molecular orientation of (t-Bu)(4)PcMg (tetra-t-butyl magnesium phthalocyanine) on polycrystalline and single crystalline gold substrates using photoemission spectroscopy and x-ray absorption spectroscopy, and we compare the results to the unsubstituted PcCu (copper phthalocyanine). The C 1s photoemission spectrum is described similar to unsubstituted relatives with an additional component for the aliphatic substituents. The variation of the excitation energy causes distinct differences in the shape of the C 1s spectrum, which is very useful for the analysis of the molecular orientation in the uppermost layer. It is shown that despite of the sterically demanding substituents, ordered sublimed films of (t-Bu)(4)PcMg are accessible, the orientation of the molecules, however, is different from the orientation of the unsubstituted relatives.
