A bifunctional compound comprising a molecular unit (I) intercalating between nucleobases (B) of nucleic acids, an active molecular unit (AD) capable of emitting a detectable signal, and optionally a spacer unit, in which the active molecular unit (AD) is selected from amongst chemical entities having a structure such as to interact electronically with the intercalating molecular unit (I) in such a way that, during the reaction of oxidation, the reduction-oxidation potential (EI+/I) of the semicouple I+/I defined by the intercalating molecular unit (I) is lower than the reduction-oxidation potential (EB+/B) of the semicouple B+/B defined by the nucleobases (B), and in such a way that, during the reaction of reduction, the reduction-oxidation potential (EI/I−) of the semicouple I/I− defined by the intercalating molecular unit (I) is higher than the reduction-oxidation potential (EB/B−) of the semicouple B/B− defined by the nucleobases (B). Moreover the use of the compound for detecting nucleic acids, a process for its synthesis, and a system comprising the same are described.

integrating an anthracene chromophore and a viologen moiety in the same molecular skeleton, joined together by a p-xylene spacer. This conjugate preserves both the DNAintercalativeproperties of the anthracene polycycle and the reversible electrochemical behavior of the viologen unit. The simultaneous presence of these components in one single molecular structure increases the affinity towards DNA in solution
