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.

First claim

What is claimed is:

1. A blue fluorescent compound represented by the following Chemical Formula 1:

where R 1 and R 2 are each selected from the group consisting of H, C 1 -C 18 saturated hydrocarbon carbons, branched saturated hydrocarbons, and saturated ring hydrocarbons, and
Ar 1 is selected from the group consisting of C 1 -C 20 aromatic compounds, heteroaromatic compounds, C 1 -C 18 saturated hydrocarbons, C 1 -C 18 branched saturated hydrocarbons, and C 1 -C 18 saturated ring hydrocarbons; and
Ar 2 is a heteroaromatic compound selected from the group consisting of:

wherein R is H, methyl, ethyl, isopropyl, tertiary-butyl, n-butyl, 1,3,5-trimethylhexyl, or aryl.

2. The blue fluorescent compound of claim 1 , wherein R 1 and R 2 are each selected from:
H, methyl, ethyl, isospropyl, tertiary-butyl, n-butyl, and 1,3,5-trimethylhexyl.

3. The blue fluorescent compound of claim 1 , wherein Ar 1 is selected from the group consisting of:

wherein R is wherein R is H, methyl, ethyl, isopropyl, tertiary-butyl, n-butyl, 1,3,5-trimethylhexyl, or aryl.

4. The blue fluorescent compound of claim 1 , wherein the blue fluorescent compound is any one selected from the compounds represented below:

5. An organic light emitting diode device comprising an organic film formed between an anode and a cathode, the organic film comprising the blue fluorescent compound of claim 1 .

6. The organic light emitting diode device of claim 5 , wherein the organic film is an emission layer.

7. The organic light emitting diode device of claim 5 , wherein the compound is used as the host of the emission layer.

8. The organic light emitting diode device of claim 5 , further comprising one or more selected from the group consisting of a hole injection layer, a hole transport layer, an electron transport layer, and an electron injection layer between the anode and the cathode.

9. The blue fluorescent compound of claim 1 , wherein Ar 2 is selected from:

10. The blue fluorescent compound of claim 9 , wherein the R substituent on Ar 2 is H or aryl.
