Polymorphism and anisotropy are fundamental phenomena of crystalline materials. However, the structure-dependent photoluminescent (PL) anisotropy in polymorphic organic crystals has remained unexplored. Herein, two polymorphic nanocrystals, green-emitting nanorods (PtD-g) and yellow-emitting nanoplates (PtD-y), were obtained from a platinum(II)-β-diketonate complex. The PtD-y crystals display remarkable
多晶性和各向异性是晶体材料的基本现象。然而,多晶型有机晶体中结构相关的光致发光 (PL) 各向异性仍未得到探索。在此,从
铂 (II)-
β-二酮络合物中获得了两种多晶型纳米晶体,即发绿光的纳米棒 (PtD-g) 和发黄光的纳米片 (PtD-y)。PtD-y 晶体显示出显着的 PL 各向异性,各向异性比高达 0.87,而 PtD-g 晶体的发射几乎未极化。这些晶体的不同分子堆积使偏振特性合理化。通过光捕获能量转移,PtD-y 晶体成功地用于放大掺杂到供体晶体基质中的发红光的
铂受体 (PtA) 的发射偏振,
