The present invention provides a µ-oxo-aluminum phthalocyanine dimer having a novel polymorph. The µ-oxo-aluminum phthalocyanine dimer may be applied to as a charge generator for an organic photoconductive material, such as a high-gamma photoreceptor which is corresponding to a short-wavelength light source(LED). The µ-oxo-aluminum phthalocyanine dimer polymorph shows diffraction peaks at a Bragg angle (2θ ± 0.2°) of 6.9°, 9.7°, 13.8°, 15.4°, 23.9°, and 25.9° in a X-ray diffraction spectrum by CuK α-ray.
本发明提供了一种具有新型多晶型的μ-氧代-铝酞菁二聚体。该µ-氧代铝酞菁二聚体可用作有机光电导材料的电荷发生器,例如与短波长光源(LED)相对应的高伽马光感受器。在用 CuK α 射线进行的 X 射线衍射谱中,μ-氧代酞菁铝二聚体多态物在布拉格角(2θ ± 0.2°)处显示出 6.9°、9.7°、13.8°、15.4°、23.9° 和 25.9°的衍射峰。
