摘要
Novel organic-inorganic hybrid compounds, C 10 H 10 N 2 PbBr 4 and C 10 H 22 N 2 PbBr 4 were prepared and characterized by X-ray and optical measurements. The result of single crystal X-ray analysis showed that the inorganic region of C 10 H 10 N 2 PbBr 4 consisted of one-dimensional chains of line-sharing PbBr 6 octahedra, whereas that of C 10 H 22 N 2 PbBr 4 consisted of two-dimensional sheets of corner-sharing PbBr 6 octahedra. Each crystal exhibited an excitonic band at 307 nm for C 10 H 10 N 2 PbBr 4 and 383 nm for C 10 H 22 N 2 PbBr 4, which is attributed to the excitonic states of low-dimensional inorganic structures. These results indicate that the dimensional structure of these compounds can be systematically controlled by changing the chemical structure of organic ligands. © 2002, Copyright Taylor & Francis Group, LLC.
