<P>PROBLEM TO BE SOLVED: To provide an organic electroluminescent element emitting dark blue light in which chromaticity change is small during performing luminance modulation. <P>SOLUTION: There is provided an organic electroluminescent element using a compound represented by the following general formula. (In the formula, n1 represents an integer of 0 to 8. R<SP POS="POST">1</SP>represents a substituent substituting a hydrogen atom of pyrene skeleton independently. X represents any one of CR<SP POS="POST">a</SP>R<SP POS="POST">b</SP>(wherein R<SP POS="POST">a</SP>, R<SP POS="POST">b</SP>each independently represent a hydrogen atom or a substituent), O, S, and SiR<SP POS="POST">d</SP>R<SP POS="POST">e</SP>(wherein R<SP POS="POST">d</SP>, R<SP POS="POST">e</SP>each independently represent a hydrogen atom or a substituent), and A<SP POS="POST">1</SP>to A<SP POS="POST">4</SP>each independently represent any one of CR<SP POS="POST">f</SP>(wherein R<SP POS="POST">f</SP>represents a hydrogen atom or a substituent, two adjacent R<SP POS="POST">f</SP>'s may together form a saturated or unsaturated ring, but two or more R<SP POS="POST">f</SP>'s can together form two or less rings), or N.) <P>COPYRIGHT: (C)2013,JPO&INPIT |
