Abstract
- A new 1D inorganic–organic hybrid [(Me 3)DAB(Me 3)]PbI 4 ·H 2 O (DAB = benzidine) with perovskite-like structure was synthesized by solvothermal method, which is consisted by 1D inorganic PbI 4 - anion chains and [(Me 3)DAB(Me 3)]2+ dications. Four [(Me 3)DAB(Me 3)]2+ cation cleverly encapsulated the folded and extended 1D chain to form a square channel. This compound can maintain high stability in various solvents and exhibit typical semiconductor behavior. In addition, this compound shows a response of 5 orders magnitude high at 100% RH. [Display omitted] • A new 1D perovskite-like material was synthesized by solvothermal method. • This compound has good chemical stability to various solvents. • This compound has a current response of 5 orders of magnitude high at 100% RH. Inorganic-Organic hybrid perovskite-like materials have potential application in photodetection, sensor and solar cells etc. However, these materials still face the challenge of poor stability. A new inorganic–organic hybrid material was synthesized by solvothermal method using H 2 DAB as the template and counter cation. The structure is composed of one-dimensional (1D) inorganic perovskite-like chain, [(Me 3)DAB(Me 3)]2+ (DAB = benzidine) dications and water molecules. This compound exhibits good stability to water and organic solvents, and shows typical semiconductor behavior. Interestingly, the compound also shows great potential for humidity sensing, including linear sensitivity (10–100%), high response (5 orders of magnitude of current change), and fast recovery time.
