Compound of the general formula (I)
X(B)m (I)
wherein
X is an m-valent unit and
B are identical or different and denote K-R, wherein
K is a bond or is A1—(A2—A3)k-sp, wherein
A1 is (CH2)tY(CH2)u, wherein
Y is >C═O, >NH, —O—, —S— or a bond,
t is an integer from 0 to 6 and
u is an integer from 0 to 6,
A2 is —NHCO—, —CONH—, —OCONH— or SCONH—, or is —CO—,
A3 is (CH2)r, O(CH2)r, NH(CH2)r, S(CH2)r or —(CHQ)—, wherein
r is an integer from 1 to 6 and
Q is a substituted or unsubstituted alkyl or aryl group,
sp is a divalent spacer or a bond, and
k is an integer from 5 to 100, and
R is hydrogen; a ligand suitable for specific bonding to a receptor; a marker molecule; or a catalytically active group; and
m is at least 2,
with the proviso that
(1) in the compound at least one R is not hydrogen,
(2) there are at least two K that are not a bond, and
(3) X, B and m are so selected that an intermolecular association of the K in liquid phase by the formation of hydrogen bonds is possible, with formation of aggregates that present on the surface a plurality of R that are not hydrogen, and
(4) the molar mass of the fragment X(K)m is less than 20,000.
