Abstract

Stepwise N-ethylation tunes N─H···Br hydrogen-bonding/steric-effect competition in homologous 1D hybrid lead bromides. The packing evolves from helical distortion to antipolar dipole cancellation and parallel polar alignment, producing chiral nonpolar, centrosymmetric antiferroelectric, and polar ferroelectric states within the same [PbBr3]− framework.

氢键/立体效应竞争驱动同源1D杂化溴化铅反铁电态和铁电态的对称分化

逐步N-乙基化调节了同源1D杂化溴化铅中N─H···Br氢键/立体效应竞争。从螺旋畸变到反极偶极抵消和平行极性排列，在相同的[PbBr3]−框架内产生手性非极性、中心对称反铁电和极性铁电态。
