diffraction for the m = 8 and m = 9 series ( n = 1-4) reveals that these compounds adopt the Cc space group for even nmembers and Pc for odd nmembers. The optical bandgaps are 2.15 eV for two-layer ( n = 2), 2.01 eV for three-layer ( n = 3), and 1.90 eV for four-layer ( n = 4). The materials exhibit excellent solution processability, and casting thin-films of the n = 3members was successfully accomplished
低维卤化物钙钛矿最近作为三维(3D)钙钛矿的替代品引起了极大的兴趣,因为它们具有更大的可调性和更高的环境稳定性。在此,我们提出了新的同源二维系列 (NH3C mH2 mNH3)(CH3NH3) n-1Pb nI3 n+1 ( m = 4-9; n = 1-4),其中 m 代表碳链数,n 等于层- 厚度编号。通过固态研磨法(m = 4 和 6)和溶液法(m = 7-9)成功合成了包含二铵阳离子的多层( n > 1)二维钙钛矿。m = 8 和 m = 9 系列 (n = 1-4) 的单晶 X 射线衍射结构表征表明,这些化合物对于偶数 n 成员采用 Cc 空间群,对于奇数 n 成员采用 Pc 空间群。两层 (n = 2), 2 的光学带隙为 2.15 eV。三层 (n = 3) 为 01 eV,四层 (n = 4) 为 1.90 eV。该材料表现出优异的溶液加工性,并且成功地完成了 n = 3 构件的浇铸薄膜。薄膜显示出较高

The incorporation of H3N(CH2)7NH3 with CH3NH3SnI3 resulted in the formation of a mixed-valent and semiconducting (Eg = 0.84 eV) organic-based perovskite, [H3N(CH2)7NH3]8(CH3NH3)2Sn(IV)Sn(II)12I46, with a unique 3D defect-perovskite structure with ordered vacancies at the Sn and I sites.
将 H3N(CH2)7NH3 与 CH3NH3SnI3 结合后,形成了一种混价半导体(Eg = 0.84 eV)有机基包晶石 [H3N(CH2)7NH3]8(CH3NH3)2Sn(IV)Sn(II)12I46,它具有独特的三维缺陷包晶石结构,在 Sn 和 I 位点上存在有序空位。
