MATERIAL FOR ORGANIC ELECTROLUMINESCENT ELEMENT AND ORGANIC ELECTROLUMINESCENT ELEMENT

摘要

A material for organic electroluminescent elements which contains a diketopyrrolopyrrole compound represented by the following general formula (1). General formula (1) (In the formula, R<SUP>1</SUP> and R<SUP>2</SUP> each independently represents (un)substituted alkylene; R<SUP>3</SUP> and R<SUP>4</SUP> each independently represents an (un)substituted aliphatic heterocyclic group or a substituent represented by the general formula (2); and R<SUP>5</SUP> to R<SUP>14</SUP> each independently represents hydrogen or a substituent, provided that at least one of R<SUP>5</SUP> to R<SUP>14</SUP> is amino represented by the general formula (3).) General formula (2) (In the formula, X represents oxygen or sulfur; and R<SUP>15</SUP> represents an (un)substituted monovalent aliphatic hydrocarbon group, (un)substituted monovalent aromatic hydrocarbon group, or (un)substituted monovalent aromatic heterocyclic group.) General formula (3) (In the formula, R<SUP>16</SUP> and R<SUP>17</SUP> each independently represents hydrogen, an (un)substituted monovalent aliphatic hydrocarbon group, (un)substituted monovalent aromatic hydrocarbon group, or (un)substituted monovalent aromatic heterocyclic group.)
