Supramolecular mating system, its preparation and use

The invention relates to a compound of formula (I), wherein R is NR R , OR or SR with R and R being H or CnH2n+1 independently of each other and being the same or different, n being a whole number from 1 to 12; R is equal to CmH2m-C(X)-Y with X being =O, =S or =N, Y being equal to OR , NR R or SR , R and R having the same meaning given above, and m being a whole number from 1 to 4; or R is equal to CmH2m-Z-Y' with Z being a sulfonyl, phosphonyl, ether or amine group, Y' being equal to H, CnH2n+1, OR , NR R or SR then Z is sulphonyl or phosphonyl group, n, R and R having the meaning given above, and Y' being equal to CnH2n+1 when Z is an ether or an amine group; A, B, and D are the same or different and mean CR R , O, NR ou S independently of each other with R , R and R being H or CnH2n+1, independently of each other, n having the meaning given above; and C is equal to CR or N with R having the meaning of R independently, A-B, B-C or C-D not being two identical heteroatoms; and nucleobase means thymine, uracile, adenine, cytosine, guanine, isocytosine, isoguanine, xanthine or hypoxanthine. The invention also relates to a method for producing these derivatives and to their use in pairing and/or testing systems.
