Chiral hybrid metal halides (CHMHs) have received a considerable amount of attention in chiroptoelectronics, spintronics, and ferroelectrics due to their superior optoelectrical properties and structural flexibility. Owing to limitations in synthesis, the theoretical prediction of room-temperature stable chiral three-dimensional (3D) CHFClNH3PbI3 has not been successfully prepared, and the optoelectronic properties of such structures cannot be studied. Herein, we have successfully constructed two pairs of chiral 3D lead iodide hybrids (R/S/Rac-3AEP)Pb2I6 (3R/S/Rac, 3AEP = 3-(1-aminoethyl)pyridin-1-ium) and (R/S/Rac-2AEP)Pb2I6 (2R/S/Rac, 2AEP = 2-(1-aminoethyl)pyridin-1-ium) through chiral introduction and ortho substitution strategies, and obtained bulk single crystals of 3R/S/Rac. The 3R/S exhibits optical activity and bulk photovoltaic effect induced by chirality. The 3R crystal device exhibits stable circularly polarized light performance at 565 nm with a maximum anisotropy factor of 0.07, responsivity of 0.25 A W−1, and detectivity of 3.4 × 1012 jones. This study provides new insights into the synthesis of chiral 3D lead halide hybrids and the development of chiral electronic devices.

手性三维有机-无机碘化铅杂化半导体
手性杂化金属卤化物（CHMH）由于其优异的光电性能和结构灵活性，在手性光电子学、自旋电子学和铁电学领域受到了广泛的关注。由于合成方面的限制，理论预测的室温稳定手性三维（3D）CHFClNH 3 PbI 3尚未成功制备，并且无法研究此类结构的光电性质。在此，我们成功构建了两对手性3D碘化铅杂化物( R / S / Rac -3AEP)Pb 2 I 6 ( 3 R / S / Rac , 3AEP = 3-(1-aminoeth)pyridin-1-ium)和( R / S / Rac -2AEP)Pb 2 I 6 ( 2 R / S / Rac , 2AEP = 2-(1-氨乙基)pyridin-1-ium)通过手性引入和邻位取代策略，得到块状单晶3 R / S / Rac 。 3 R / S表现出光学活性和由手性引起的体光伏效应。 3 R晶体器件在565 nm处表现出稳定的圆偏振光性能，最大各向异性因子为0.07，响应度为0.25 AW -1 ，探测灵敏度为3.4 × 10 12琼斯。这项研究为手性 3D 卤化铅杂化物的合成和手性电子器件的开发提供了新的见解。
