The response of crystal structure to external stimuli provides potential applications in the areas of detection, diagnosis, and repair. In this work, we fabricate two allotropic organic cocrystals, with different space groups and lattice parameters, with identical donor and acceptor molecules inside them. Under external stimuli, lattice vibration and electron–phonon coupling present pronounced differences in these two types of crystals, where different strengths of spin polarizations are observed. Furthermore, due to pronounced differences in coupling between lattice and spin inside the allotropic charge transfer crystals, the magnetic field presents a discrepant tunability on both transmission and fluorescence lifetimes. Through decreasing temperature or applying external electric field, the electron–phonon coupling coefficient presents a decreasing tendency, which will affect the dipole and dielectric constant in the allotropic crystals differently.

有机共晶中通过自旋晶格耦合的机械响应自旋
晶体结构对外部刺激的反应在检测、诊断和修复领域提供了潜在的应用。在这项工作中，我们制造了两个同素异形有机共晶，它们具有不同的空间群和晶格参数，内部具有相同的供体和受体分子。在外部刺激下，晶格振动和电子 - 声子耦合在这两种类型的晶体中表现出明显的差异，其中观察到不同强度的自旋极化。此外，由于同素异形电荷转移晶体内部晶格和自旋之间耦合的显着差异，磁场在透射和荧光寿命上呈现出差异的可调性。通过降低温度或施加外部电场，
