Abstract
Disclosed are a compound that emits fluorescence, particularly in its solid state, and is suited to provide a color converting material with various improved performance properties over prior art and a light emitter, a color conversion filter, a color conversion device, and a photoelectric device each containing the compound; particularly a Schiff base type compound of formula (I) and a coloring material, a color conversion layer, a light absorbing layer, a color conversion filter, a light absorbing filter, a color-converting light-emitting device, and a photoelectric device each containing the compound. The definition of the symbols in formula (I) is the same as in the specification.
Claims20
A Schiff base type compound represented by general formula (I):
- wherein
- ring A represents an aromatic ring, an aliphatic ring, or a heterocyclic ring;
- Ar represents a 5- or 6-membered heterocyclic or aromatic ring;
- and
- X represents a halogen atom,
- the aliphatic ring represented by ring A and the aromatic ring and the heterocyclic ring represented by ring A or Ar being optionally fused to a ring or optionally substituted,
- at least one of the hydrogen atoms bonded to ring A or Ar being displaced by an amino group represented by —NR″R′″, wherein R″ and R′″ each represent an alkyl group having 1 to 10 carbon atoms or an aryl group having 6 to 10 carbon atoms and may be each taken together with ring A or Ar to form a ring structure.
