A three-dimensional-two-dimensional dimensionality transition of organic microcrystals was performed via elongated octahedrons, oblique octahedrons, diamond-like particles, and parallelograms using nonplanar 2,7-di(9-carbazol-9-yl)spiro[fluorene-9,9'-xanthene] molecules. The specific crystal symmetry and selective adhesion of P123 on the {11-1}s facet are supposed to induce the morphological transition.
通过使用非平面的2,7-二(9-咔唑-9-基)螺[芴-9,9'-呫吨]分子,经由细长八面体、斜八面体、类金刚石颗粒和平行四边形实现了有机微晶的三维-二维维度转变。推测P123在{11-1}s晶面上的特定晶体对称性和选择性粘附会诱导形态转变。
