Synthesis in Ionic Liquids: [Bi2Te2Br](AlCl4), a Direct Gap Semiconductor with a Cationic Framework
The Lewis acidic ionic liquid EMIMBr-AlCl3 (EMIM = 1-ethyl-3-methylimidazolium) allows a novel synthetic route to the semiconducting layered metal chalcogenides halide [Bi2Te2Br](AlCl4) and its Sb analogue. [Bi2Te2Br](AlCl4) is a direct band gap, strongly anisotropic semiconductor and consists of cationic infinite layers of [Bi2Te2Br](+) and [AlCl4](-) anions inserted between the layers.
