Abstract

The layered structure of organic-inorganic perovskite hybrids, $(C_nH_{2n+1}NH_3)_2CuC1_4$ (n = 6, 8, 10, 12) have synthesized. In $(C_nH_{2n+1}NH_3)_2CuC1_4$ compounds, the long-chain protonated alkylammonium ions as tilted bilayer type are inserted into perovskite-type layers of corner sharing $CuCl_6$ octahedron. Three solid phases have been characterized in the perovskite layered compound $(C_nH_{2n+1}NH_3)_2CuC1_4$ using HT-XRD and DSC. The $(C_nH_{2n+1}NH_3)_2CuC1_4$ compounds shows solid-solid phase transitions with stepwise increasing of the layer distance. Three different structures are explained by the conformational change of the long-chain protonated alkylammonium ions.

층상 구조의 유기-무기 페로브스카이트 복합 소재 $(C_nH_{2n+1}NH_3)_2CuC1_4$ (n=6, 8, 10, 12)을 합성하였다. $(C_nH_{2n+1}NH_3)_2CuC1_4$ 화합물에서 긴 사슬의 양성자화된 알킬 암모늄 이온은 기울어진 이중층의 구조로 $CuCl_6$ 팔면체의 구석을 공유하고 있는 페로브스카이트형의 층들 사이에의 삽입되었다. 페로브스카이트 층상 화합물에서의 3개의 고체상을 HT-XRD와 DSC를 사용하여 조사하였다. $(C_nH_{2n+1}NH_3)_2CuC1_4$ 화합물은 단계적인 층간거리의 증가와 함께 고체-고체 상전이 현상을 보여준다 3개의 다른 구조는 긴 사슬의 양성자화된 알킬 암모늄 이온의 형태 변화로 설명하였다.
