Anisotropic organic single‐crystalline materials can induce abundant SOC phenomenon due to their flexible tunability of molecular geometries, however, the intrinsic relationship between molecular geometries/orientations in 3D space and photonic SOC is lacking. In this study, we design two kinds of 2D organic polymorphs for the construction of organic microcavities to investigate the structure‐performance relationships. In two polymorphic microcavities, two distinctive photonic SOC phenomena are observed regardless of the in‐plane anisotropy of organic polymorphs. Theoretical analysis indicates that the photonic SOC strength is strongly influenced by the synergies between the crystal anisotropy and the tilted collective molecular transition dipole moment. Our results uncover the correlation mechanism between the structure of molecules and photonic SOC and open an avenue to engineer complex photonic SOC by use of organic microstructures towards the development of diverse integrated photonic devices." article_number: e01874 author: - first_name: Ying full_name: Ji, Ying last_name: Ji - first_name: Xuekai full_name: Ma, Xuekai id: '59416' last_name: Ma - first_name: Han full_name: Huang, Han last_name: Huang - first_name: Yibo full_name: Deng, Yibo last_name: Deng - first_name: Pingyang full_name: Wang, Pingyang last_name: Wang - first_name: Teng full_name: Long, Teng last_name: Long - first_name: Yuan full_name: Li, Yuan last_name: Li - first_name: Ruiyang full_name: Zhao, Ruiyang last_name: Zhao - first_name: Yunfei full_name: Li, Yunfei last_name: Li - first_name: Cunbin full_name: An, Cunbin last_name: An - first_name: Stefan full_name: Schumacher, Stefan id: '27271' last_name: Schumacher orcid: 0000-0003-4042-4951 - first_name: Chunling full_name: Gu, Chunling last_name: Gu - first_name: Bo full_name: Liao, Bo last_name: Liao - first_name: Hongbing full_name: Fu, Hongbing last_name: Fu - first_name: Qing full_name: Liao, Qing last_name: Liao citation: ama: Ji Y, Ma X, Huang H, et al.
