1. An elastomer composition comprising an adduct between an sp2 hybridized carbon allotrope and a compound of formula (I)

OG Complex Work Unit Chemistry
wherein the compound of formula (I) may be linear or cyclic and the symbol (C) does not represent a bond when the compound is linear and represents a bond when the compound is cyclic, and
X1, X2 X3, X4, X5 are selected independently from the group consisting of O, N—R7, halogen and S;
and wherein if X1, X2, X3, X4, X5 are halogen, R1, R2, R3, R4, R5 are absent;
and wherein:
the compound of formula (I) is linear when:
m and n are 1 and Y is selected from the group consisting of O, N—R7 and S; or
m is 1 and n is 0 and Y is halogen and
when the compound is linear, the symbols (A) and (B) represent independently a single or a double bond, and
if the symbols (A) and (B) are a double bond, v, u, p and q are 0;
if the symbols (A) and (B) are a single bond, v, u, p, q are 1;
if the symbol (A) is a double bond and the symbol (B) is a single bond, v and p are 0 whereas u and q are 1;
if the symbol (B) is a double bond and the symbol (A) is a single bond, v and p are 1 whereas u and q are 0;
the compound of formula (I) is cyclic when:
the symbols (A) and (B) are a double bond, and
m, v, p, q and u are 0, and
if Y is O, n is 0, or if Y is N, n is 1;
and wherein:
if X1 and Y are NR7 or S, then:
R1, R6 are selected independently from the group consisting of: hydrogen, linear or branched C1-C6 alkyl, linear or branched C2-C6 alkenyl or alkynyl, aryl, linear or branched C1-C6 alkyl-aryl, linear or branched C2-C6 alkenyl-aryl, linear or branched C2-C6 alkynyl-aryl, heteroaryl;
if X1 and Y are O, then:
R1, R6 are selected independently from the group consisting of: hydrogen, linear or branched C1-C6 alkyl, linear or branched C2-C6 alkenyl or alkynyl, aryl, linear or branched C1-C6 alkyl-aryl, linear or branched C2-C6 alkenyl-aryl, linear or branched C2-C6 alkynyl-aryl, heteroaryl, alkali metals, alkaline-earth metals, transition metals, or
