  A composition comprising: at least one compound comprising a hole transporting core, wherein the core is covalently bonded to a first arylamine group and also covalently bonded to a second arylamine group different from the first, and wherein the compound is covalently bonded to at least one intractability group, wherein the intractability group is covalently bonded to the hole transporting core, the first arylamine group, the second arylamine group, or a combination thereof, and wherein the compound has a molecular weight of about 5,000 g/mole or less. Blended mixtures of arylamine compounds, including fluorene core compounds, can provide good film formation and stability when coated onto hole injection layers. Solution processing of OLEDs is a particularly important application.

  The invention is a process for producing a propylene glycol monoalkyl ether which comprises first reacting propylene oxide and an alcohol in the presence of an alkali or alkaline earth metal alkoxide catalyst to produce an alkoxylation mixture comprising propylene glycol monoalkyl ether; distilling the alkoxylation mixture to produce a first overhead stream comprising propylene oxide and alcohol and a first bottoms stream comprising propylene glycol monoalkyl ether; and then distilling the first bottoms stream to produce purified propylene glycol monoalkyl ether as a second overhead stream. The reaction and/or one or more of the distillation steps occur in the presence of an alkali metal borohydride. The process produces propylene glycol monoalkyl ether with low UV absorbance and reduced carbonyl impurities.
