Abstract
A lead(II) organic-inorganic hybrid perovskite material [(TMA)2(MA)2Pb3I10] (1) has been synthesized by reactions of 2-thienylmethylamine (TMA) and methylamine (MA) with PbI2 in HI/H3PO2 aqueous solution. The crystallographic diffraction indicated the inorganic moiety in 1 is a trilayered perovskite structure constructed with [PbI6] octahedra, and the two organic amines are located between the inorganic layers, or embedded in the octahedral cavity of inorganic layers. The solid UV–vis absorption peak of compound 1 is located at 600 nm, and the bandgap calculated by DFT is 1.60 eV, both indicating it is a semiconductor and has potential application in organic-inorganic hybrid solar cell.
