    Abstract: Described are compounds that are capable of forming adlayers, said compounds comprising at least one headgroup A, an optional linker B, a polymer C, a terminal group D and an optionally present crosslinking group R, wherein the headgroup A is a compound of the following formula wherein X is independently from each other selected from an acidic group, such as OH, SH, phosphate, phosphornate and N + R 2 H, Y is a group derived from a convenient coupling group, in particular NL 3 , or N + (L 3 )2, Z 1 , Z 3 , and Z 4 are C or N + Z 2 , Z 5 and Z 6 are C-L 1 or N + -L, wherein L 1 is H or an electron withdrawing group, L is C 1 -C 6 alkyl, in particular C 1 -C 4 alkyl L 2 and L 3 are independently selected from H or C 1 -C 6 alkyl, preferably C 1 -C 4 alkyl, or L 2 may form together with L 1 or L of Z 6 a heterocycle, in particular a positively charged heterocycle, n is 0, or 1, or 2, or 3, m is 0 or 1 with the proviso that at most one of Z 1 to Z 6 is N + and that in case that Z 1 is N + , L 2 may additionally be an ester, an amide, or a heterocycle.
