General description

Hydrobromic acid is a strong acid that can be used as a brominating reagent for the electrophilic and radical bromination of olefins, alkynes, and ketones.

Application

Hydrobromic acid can be used as a brominating agent for the:
  • Bromination of benzothiadiazoles and methylamines.
  • Oxidative bromination of olefins, alkynes, and ketones to corresponding dibrominated alkanes, alkenes, and α-bromoketones.

Lead-free double perovskites have great potential as stable and nontoxic optoelectronic materials. Recently, Cs2 AgBiBr6 has emerged as a promising material, with suboptimal photon-to-charge carrier conversion efficiency, yet well suited for high-energy photon-detection applications. Here, the optoelectronic and structural properties

The room-temperature charge carrier mobility and excitation-emission properties of metal halide perovskites are governed by their electronic band structures and intrinsic lattice phonon scattering mechanisms. Establishing how charge carriers interact within this scenario will have far-reaching consequences for developing high-efficiency
