利用单色同步辐射测量了在MoS 2解理衬底上的酞菁铜(CuPc)和无金属酞菁(H2 Pc)薄膜(厚度从单层到50-80)的角分辨紫外光电子能谱(ARUPS)。利用单散射近似理论结合分子轨道计算,定量分析了顶π带强度与发射角(θ)和方位角(φ)的关系.分析表明,在CuPc和H_2Pc的单层膜中,MoS_2表面的分子是平的。分子的方位角取向(分子轴和二硫化钼表面晶轴之间的角度),对于CuPc和H2 Pc的单层膜都发现约为−7°、−37°或−67°。在方位角方向,分析表明,只有逆时针旋转的分子,虽然顺时针和逆时针旋转的预期。从低能电子衍射,二维晶格…
Angle-resolved ultraviolet photoelectron spectra (ARUPS) of copper phthalocyanine (CuPc) and metal-free phthalocyanine (H2Pc) films (thickness from monolayer to 50–80 A) on cleaved MoS2 substrates were measured using monochromatic synchrotron radiation. Observed take-off angle (θ) and azimuthal angle (φ) dependencies of the top π band intensity were analyzed quantitatively by the single-scattering approximation theory combined with molecular orbital calculations. The analysis indicated that the molecules lie flat on the MoS2 surface in monolayer films of CuPc and H2Pc. The azimuthal orientation of the molecules (angle between molecular axis and surface crystal axis of MoS2), was found to be about −7°, −37°, or −67° for both monolayer films of CuPc and H2Pc. In the azimuthal orientation, the analyses indicated that there are only molecules with conterclockwise rotation, although both clockwise and counterclockwise rotations are expected. From the low energy electron diffraction, the two-dimensional lattice...
