Bromination of hydrocarbons with CBr4, initiated by light-emitting diode irradiation
Beilstein Journal of Organic Chemistry, 2013 The bromination of hydrocarbons with CBr4 as a bromine source, induced by light-emitting diode (LED) irradiation, has been developed. Monobromides were synthesized with high efficiency without the need for any additives, catalysts, heating, or inert ...

Efficient in‐Plane Exciton Transport in a Discontinuous Layered Lead‐Bromide Perovskite
Advanced Materials, EarlyView.A new class of two‐dimensional lead‐bromide perovskite based on monovalent 4‐aminomethylbenzoic acid cations is presented, featuring a discontinuous inorganic layer. Despite the discontinuous lattice, transient photoluminescence microscopy demonstrates efficient though strongly anisotropic in‐plane exciton transport.
