- Abstract
Cyclic organic amines are emerging as excellent building blocks to assemble organic–inorganic hybrid phase transition materials due to their flexible cyclic structure. Here, we have assembled a 1D organic‐inorganic hybrid dielectric material C5H6NOPbBr3 (1) by alloying the cyclic organic amine 3‐hydroxypyridine. 1 displays a remarkable switchable dielectric response induced by an order‐disorder transformation of the organic moiety, this transformation behaviour is confirmed by DSC and Hirshfeld surface measurements. More interestingly, 1 has a narrowband emission (FWHM=4.64 nm) at 590 nm; FWHM is a major quality figure for narrowband photodetectors. In addition, 1 exhibits semiconducting properties with an indirect bandgap of 2.78 eV by the analysis of the UV‐Vis absorption results.
