The present teachings relate to organic semiconductor formulations including an organic semiconducting compound in a liquid medium, where the liquid medium includes (1) a compound in liquid state that has electronic properties complementary to the electronic structure of the organic semiconducting compound and optionally (2) a solvent or solvent mixture for solubilizing the organic semiconducting compound. The present formulations can be used as inks in the fabrication of organic semiconductor devices.

carbazoles through gold(I)-catalyzed intramolecular hydroarylation of (Z)-2-(enynyl)indoles was achieved in good yields. The requisite (Z)-2-(enynyl)indoles were synthesized stereoselectively by trimethylgallium-promoted, Z-selective Wittig olefination of N-alkylindole-2-carboxaldehydes with propargyl ylides. Substrates possessing both alkyl as well as aromatic groups are well tolerated under these reaction
