The luminescence properties of three neutral cyclometalated Pt(II) complexes were investigated in a CH₂Cl₂/n-hexane system. The diphenylamino and trifluoromethyl modified Pt2 exhibits aggregation-induced phosphorescent emission (AIPE) feature. The crystal stacking of Pt2 shows that the intermolecular hydrogen bonding restricts both intramolecular rotation (RIR) and vibration (RIV), which weakens the non-radiative decay ways and leads to an AIPE performance. TEM images reveal that Pt2 aggregates into nanosheets.

环金属化的铂发光特性（II）在二氯甲烷络合物/ Ñ己烷系统

在CH ₂ Cl ₂ / n-己烷体系中研究了三种中性环金属化的Pt（II）配合物的发光特性。二苯氨基和三氟甲基修饰的Pt2表现出聚集诱导的磷光发射（AIPE）功能。Pt2的晶体堆积表明，分子间氢键限制了分子内旋转（RIR）和振动（RIV），这削弱了非辐射衰减方式并导致了AIPE性能。TEM图像显示Pt2聚集成纳米片。
