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.
一种组合物,包括:至少一种包含空穴传输核的化合物,其中该核与第一芳胺基团共价键合,并且也与第二个与第一不同的芳胺基团共价键合,且该化合物与至少一个难处理性基团共价键合,其中该难处理性基团与空穴传输核、第一芳胺基团、第二芳胺基团或其中的组合物共价键合,且该化合物的分子量约为5,000 g/mol或更低。芳胺化合物的混合物,包括芴核化合物,可以在涂覆空穴注入层时提供良好的膜形成和稳定性。 OLED的溶液加工是一个特别重要的应用。
