共轭聚合物骨架的平面芳香性质使其具有各向异性。在这里，我们证明了含硫半晶共轭聚合物在硫k边的共振x射线衍射是高度各向异性的，衍射强度的调制取决于入射光束相对于衍射晶体平面的偏振方向。通过确定各向异性共振散射因子，我们可以基于提出的聚合物的单元几何结构，从光谱上再现所观察到的共振各向异性散射效应。
The planar, aromatic nature of the backbone of conjugated polymers endows them with anisotropic properties. Here we show that the resonant X-ray diffraction of a sulfur-containing semicrystalline conjugated polymer at the sulfur K-edge is highly anisotropic, with strong modulation of diffracted intensity depending upon the relative orientation of the polarization of the incident beam with respect to the diffracting crystal planes. Through determination of the anisotropic resonant scattering factors, we can spectroscopically reproduce the observed resonant anisotropic scattering effects based on a proposed unit cell geometry for the polymer.
