A new corner-shared 1D hybrid lead halide: Broad-band photoluminescence and semiconductive properties.

A new 1D hybrid lead halide (dbod)Pb 2 Br 6 was synthesized by solvothermal method with 1,4-Diazoniabicyclo[2.2.2]octane, 1,4-dipropy2+ ((dobd)2+) as organic spacer and counter cation. [PbBr5] pyramids in the structure connects with each other through corner-sharing to constitute continuous [Pb 2 Br 6 ]2+ chains. The compound shows broad band orange emission under UV excitation and good conductivity at room-temperature. The material system hold potential for the application of white-light emitting diodes. [Display omitted] • A new 1D corner-shared hybrid lead bromide was synthesized by solvothermal method. • The compound exhibits broad band orange emission under UV excitation. • This compound shows a good conductivity at room- temperature. Hybrid metal halides with high chemistry versatility and electronic tunability is a promising material system for new-generation lighting and displaying. Lowing the dimensionality of inorganic moieties gives rise to the broad-band white emission of those materials. Here a new 1D hybrid lead bromide (dbod)Pb 2 Br 6 (dbod2+=1,4-Diazoniabicyclo[2.2.2]octane, 1,4-dipropy2+) was synthesized using organic dbod2+ as the spacer and balance cation. The compound showed a very broad emission with a full width half-maximum of 244 nm. With good electron conductivity, this series of compounds hold potential for the application of white-light LEDs.
