Abstract
A π-conjugated compound having a cardo structure of formula (1): where R1 and R2 are hydrogen, alkyl, alkoxy, phenyl, naphthyl, phenoxy or halogen; Ar1 is a group of formula (2) or (3): where R3 thru R6 are hydrogen, alkyl, alkoxy, aryl, hetero-aryl, aryloxy or a halogen, and l and m are 0-3, and n is 0-2; and Ar2 is aryl or hetero aryl. The π-conjugated compound has good stability and is used as light emitting material.
Claims8
A π-conjugated compound having a cardo structure represented by the following formula (1):
- where R1 and R2 independently represent a hydrogen atom, a straight-chain, branched or cyclic alkyl or alkoxy group having 1 to 18 carbon atoms which may have a substituent, a phenyl, naphthyl or phenoxy group which may have a substituent, or a halogen atom;
- Ar1 independently represents a group represented by the following formula (2) or (3):
- where R3 through R6 independently represent a hydrogen atom, a straight-chain, branched or cyclic alkyl or alkoxy group having 1 to 18 carbon atoms which may have a substituent, or an aryl or aryloxy group having 6 to 24 carbon atoms which may have a substituent other than an amino group, or a heteroaryl group having 3 to 24 carbon atoms which may have a substituent other than an amino group, or a halogen atom, and l and m are integers of 0 to 3, and n is an integer of 0 to 2;
- and
- Ar2 independently represents an aryl group having 6 to 24 carbon atoms which may have a substituent other than an amino group, or a heteroaryl group having 3 to 24 carbon atoms which may have a substituent other than an amino group.
