主权项

1. A composition comprising at least one non-polymeric organic ionic compound and at least one non-ionic organic functional compound, wherein the organic ionic compound is a compound of formula (1):
(M)m+/−y×(N)n−/+  Formula (1); wherein: M is an organic ion having the charge m+ or m−; N is an organic or inorganic counter ion being the same or different at each occurrence having the charge n− or n+; m indicates the number of the charge of M and is an integer of ≧2; y indicates the number of N, and is an integer of ≧1; n indicates the number of the charge of N and is an integer of ≧1; wherein the net charge of the compound of formula (1) is zero; and wherein the non-ionic organic functional compound is selected from the group consisting of host materials, phosphorescent emitters, fluorescent emitters, hole transporting materials (HTM), hole injecting materials (HIM), electron transporting materials (ETM), and electron injecting materials (EIM).
