wherein A is an oligomer group comprising carbon and fluorine;
B is —(CH 2 )x-, wherein x is an integer of 0 to 12;
D is carbon or silicon;
each of E1 to E3 is, independently from one another, H, —X1-[(CH 2 )y-X2]z, or —(CH 2 )y-X3, wherein at least one of E1 to E3 is not H;
y is an integer of 0 to 8;
z is an integer of 1 to 3;
X1 is oxygen, nitrogen, sulfur, carbon, or phosphorus; and
each of X2 and X3, independently from one another, includes a hydroxy group, a dimethyl monoalkoxysilane group, a monomethyldialkoxysilane group, a trialkoxysilane group, a silazane group, an amine group, an ethylene glycol group, a triethylene glycol group, a mercapto group, an ester group, an alkoxy group, a methacrylic group, an acrylic group, a carboxylic acid group, a cyclic amine group, an epoxy group, a fluorocarbon group, an azide group, a benzophenone group, or an isocyanate group,
wherein the compounds of Chemical Formula 1 comprise:
a first compound with a molecular weight of the group A of about 270 to about 930 in Chemical Formula 1,
a second compound with a molecular weight of the group A of about 1,800 to about 2,200 in Chemical Formula 1, and
a third compound with a molecular weight of the group A of about 3,600 to about 4,400 in Chemical Formula 1.

2. The coating composition of claim 1 , wherein weight ratios of the first, second, and third compounds of the coating composition are:
the first compound to the second compound is about 0.9:1 to about 1.1:1;
the second compound to the third compound is about 0.9:1 to about 1.1:1; and
the third compound to the first compound is about 0.9:1 to about 1.1:1.

3. The coating composition of claim 1 , wherein
the first, second, and third compounds are compounds of Chemical Formula 6:

wherein a is a perfluoropolyether group;
n1 is an integer of 0 to 12;
n2 is an integer of 1 to 8;
n3 is an integer of 1 to 3;
each of n4 and n5 is, independently from one another, an integer of 0 to 3 with the proviso that n4+n5=3;
the X1 is oxygen, nitrogen, sulfur, carbon, or phosphorus; and
each of X2 and X3, independently from one another, is a hydroxy group, a dimethyl monoalkoxysilane group, a monomethyldialkoxysilane group, a trialkoxysilane group, a silazane group, a primary amine group, a secondary amine group, a tertiary amine group, an ethylene glycol group, a triethylene glycol group, a mercapto group, an ester group, an alkoxy group, a methacrylic group, an acrylic group, a carboxylic acid group, a cyclic amine group, an epoxy group, a fluorocarbon group, an azide group, a benzophenone group, or an isocyanate group.

4. A coating composition including a compound of Chemical Formula 1:

wherein A is an oligomer group comprising carbon and fluorine;
B is —(CH 2 )x-, wherein x is an integer of 0 to 12;
D is carbon or silicon;
each of E1 to E3 is, independently from one another, H, —X1-[(CH 2 )y-X2]z, or —(CH 2 )y-X3, wherein at least one of E1 to E3 is not H;
y is an integer of 0 to 8;
z is an integer of 1 to 3;
X1 is oxygen, nitrogen, sulfur, carbon, or phosphorus; and
each of X2 and X3, independently from one another, includes a hydroxy group, a dimethyl monoalkoxysilane group, a monomethyldialkoxysilane group, a trialkoxysilane group, a silazane group, an amine group, an ethylene glycol group, a triethylene glycol group, a mercapto group, an ester group, an alkoxy group, a methacrylic group, an acrylic group, a carboxylic acid group, a cyclic amine group, an epoxy group, a fluorocarbon group, an azide group, a benzophenone group, or an isocyanate group,
wherein the group A includes a group of Chemical Formula 3:

wherein in Chemical Formula 3, each of d, e, f, g, and h is, independently from one another, an integer of 0 to 50.

5. A coating composition including a compound of Chemical Formula 1:

wherein A is an oligomer group comprising carbon and fluorine;
B is —(CH 2 )x-, wherein x is an integer of 0 to 12;
D is carbon or silicon;
each of E1 to E3 is, independently from one another, H, —X1-[(CH 2 )y-X2]z, or —(CH 2 )y-X3, wherein at least one of E1 to E3 is not H;
