TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Composition: The ink further comprises dopant or an alkali dopant, or a compound of formula (M2MB1 (E1R2)4) or (M2(E1R2)).M2 = Li, Na or K; andR2 = alkyl or aryl.The ink further comprises at least one component containing surfactant, dispersant, emulsifier, anti-foaming agent, dryer, filler, resin binder, thickener, viscosity modifier, anti-oxidant, flow agent, plasticizer, conductivity agent, crystallization promoter, extender, film conditioner or adhesion promoter. Preferred Components: The ink is a solution of compounds in an organic carrier. The carrier is aliphatic hydrocarbons, aromatic hydrocarbons, pentane, hexane, heptane, octane, isooctane, decane, cyclohexane, para-xylene, meta-xylene, ortho-xylene, benzene, toluene, xylene, ethers, diethyl ether, tetrahydrofuran, 2-methyltetrahydrofuran, siloxanes, cyclosiloxanes, silicone fluids, acetonitrile, esters, acetates, ethyl acetate, butyl acetate, acrylates, isobornyl acrylate, ketones, acetone, methyl ethyl ketone, cyclohexanone, cyclopentanone, lactams, N-methylpyrrolidone, N-(2-hydroxyethyl)-pyrrolidone, cyclic acetals, cyclic ketals, aldehydes, alcohol, methanol, ethanol, isopropyl alcohol, thiols, butanol, butanediol, glycerols, alkoxyalcohols, glycols, 1-methoxy-2-propanol, acetone, ethylene glycol, propylene glycol, propylene glycol laurate, ethylene glycol ethers, diethylene glycol, triethylene glycol monobutylether, propylene glycol monomethylether and/or 1,2-hexanediol. The viscosity of the ink is 0.5-50 centipoises (cP), preferably 2-12 cP. Preferred Definitions:    MB1 = In or Ga;    E1 = Se; and    R1 = n-propyl, isopropyl, n-butyl, isobutyl, secondary-butyl, tert-butyl, ethyl and/or n-pentyl.    EXAMPLE - Indium selenium and secondary-butyl of formula (In(SeBu)3) and gallium selenium and secondary-butyl of formula (Ga(SeBu)3) were mixed in a 70:30 indium/ gallium ratio in cyclohexane to 50 wt.% molecule content, followed by dilution with heptane to give 30 wt.% molecule content in an inert atmosphere glove box, to obtain ink.
