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.
一种组分,包括:至少一种包含传输空穴核的化合物,其中该核与第一芳胺基团和与第一芳胺基团不同的第二芳胺基团共价键合,且该化合物与至少一种难溶性基团共价键合,其中该难溶性基团与传输空穴核、第一芳胺基团、第二芳胺基团或其组合之一共价键合,且该化合物的分子量约为5,000克/摩尔或更低。芳胺化合物的混合物,包括芴核化合物,当涂覆到空穴注入层时,可以提供良好的膜形成和稳定性。 OLEDs的溶液处理是一个特别重要的应用。
