The pseudohalogens are polyatomic analogues of halogens, whose chemistry, resembling that of the true halogens, allows them to substitute for halogens in several classes of chemical compounds. Pseudohalogens occur in pseudohalogen molecules, inorganic molecules of the general forms Ps–Ps or Ps–X (where Ps is a pseudohalogen group), such as cyanogen; pseudohalide anions, such as cyanide ion; inorganic acids, such as hydrogen cyanide; as ligands in coordination complexes, such as ferricyanide; and as functional groups in organic molecules, such as the nitrile group. Well-known pseudohalogen functional groups include cyanide, cyanate, thiocyanate, and azide.
Organic room-temperature phosphorescent material and electroluminescent device
PendingCN110724088AImprove structural stabilityLong room temperature phosphorescenceOrganic chemistry methodsSolid-state devicesBenzeneChemical physics
The invention discloses an organic room-temperature phosphorescent material and an electroluminescent device. The material is based on a structure with 1,3-dicarbazolyl benzene as a mother nucleus andmodified by halogen atoms or pseudo-halogen groups, may have very long room-temperature phosphorescence (with lifetime as long as several seconds), and also has very high phosphorescent quantum yield(up to 40% or above). Furthermore, on the basis of the structure, the structural stability of molecules can be improved by introducing a modification group or deuteration to a carbazolyl group, and phosphorescence lifetime can be further prolonged by deuteration because of the self heavy-atom effect, so triplet-state molecular orbital coupling effect is improved. Furthermore, a series of new mother nucleuses are designed through the replacement of carbazole similar structures and the replacement of phenyl groups, but the main body structure is not changed, and super-long room-temperature phosphorescence and strong phosphorescence quantum yield are also realized after the same modification.
