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.
Claims8
A color conversion layer, comprising a coloring material comprising:
- at least one Schiff base type compound represented by general formula (I):
- and
- a binder resin,
- 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, and
- rings A and Ar are unsubstituted, or at least one of the hydrogen atoms bonded to ring A or Ar is substituted by an alkyl group, an alkoxy group, an alkylthio group, an alkenyl group, an arylalkylgroup, an aryl group, an aryloxy group, an arylthio group, a heterocyclic group, a halogen atom, an acyl group, an acyloxy group, a sulfonamide group, a sulfonyl group, a carboxyl group, a cyano group, a sulfo group, a hydroxyl group, a nitro group, a mercapto group, an imido group, or a carbamoyl group.
A light absorbing layer, comprising a coloring material comprising:
- at least one Schiff base type compound represented by general formula (I):
- and
- a binder resin,
- 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, and
- rings A and Ar are unsubstituted, or at least one of the hydrogen atoms bonded to ring A or Ar is substituted by an alkyl group, an alkoxy group, an alkylthio group, an alkenyl group, an arylalkyl group, an aryl group, an aryloxy group, an arylthio group, a heterocyclic group, a halogen atom, an acyl group, an acyloxy group, a sulfonamide group, a sulfonyl group, a carboxyl group, a cyano group, a sulfo group, a hydroxyl group, a nitro group, a mercapto group, an imido group, or a carbamoyl group.
