A blue fluorescent compound is disclosed. The blue fluorescent compound represented by the following Chemical Formula 1,
where R1 and R2 are each independently selected from the group consisting of C0-C18 saturated hydrocarbon carbons, branched saturated hydrocarbons, and saturated ring hydrocarbons, and Ar1 and Ar2 are each independently selected from the group consisting of C1-C20 aromatic compounds, heteroaromatic compounds, C1-C18 saturated hydrocarbons, C1-C18 branched saturated hydrocarbons, and C1-C18 saturated ring hydrocarbons.
Aspects of the present invention provide a naphtho[2,1-b]fluoranthene compound represented by the following general formula [1], which has property of high electron injection.
In the formula [1], R
1
and R
2
are respectively selected from the group consisting of hydrogen atom, an alkyl group having 1 to 4 carbon atoms, an alkoxy group having 1 or 2 carbon atom, a halogen atom and a cyano group. Ar
1
denotes a bivalent aromatic hydrocarbon having 6 to 24 carbon atoms. Ar
2
denotes a monovalent aromatic hydrocarbon having 6 to 24 carbon atoms. The integer n is from 0 to 3. In a case where n is 2 or more, each Ar
1
may be the same or different.
