Abstract
The present invention relates to a dinitroxide biradical compound of general formula (I): In formula (I), A is a carbon, an ammonium, or a phosphonium; each of A1 to A6 is a single bond, O, N, N(O), S, S(O), SO, C(O), or a (C1-C4) alkyl chain; and Z1 and Z2 are selected from R1 and R2 in combination, so that there is always at least one R2 group that is substituted with R3 group. In Z1 and Z2, R1 is an H, an aryl, or a heteroaryl; R2 is an alkyl chain, an alkenyl chain, an alkynyl chain, a cycloalkyl, a heterocycloalkyl, an aryl, or a heteroaryl; and R3 is an alkyl chain, an alkenyl chain, an alkynyl chain, a cycloalkyl, a heterocycloalkyl, an aryl, a heteroaryl, an ether, an ester, or an azide. When Z1 and Z2 are combined together with the same carbon atom of the nitroxide ring to which they are bonded, they form a spirocycloalkyl or a spiroheterocycloalkyl, the spirocycloalkyl or the spiroheterocycloalkyl being substituted with R3.
