<p>New compounds for making a hydrophilic surface lipophilic. The compouns have general formula (I), wherein Z?1 and Z2¿ independently is chlorine, fluorine, bromine, alkoxy with not more than 6 carbon atomes, NH, -NH¿2?, -NR2, wherein R' is alkyl with 1 to 3 carbon atoms, -SH, -CN, - N3 or hydrogen, and R?1¿ is formula (II), wherein each S-substituent which can be the same or different is hydrogen, whereby the phenyl ring may contain at the most four hydrogen substituents, alkyl with 2 to 4 carbon atoms, or methyl or methoxy, in which case there may be at the most three hydrogen substituents in the phenyl ring, cyano, ethoxy, or two adjacent S-substituents form with the phenyl nucleus a naphtalene or anthracene group, or three adjacent S-substituents form together with the phenyl nucleus a pyrene group, and X is the group -(CH¿2?)n$(1,4)$, wherein n is 0 to 20, preferably 10 to 16, or the group (III), wherein i is 0 to 10 and k is 1 to 5, whereby, when n is not 0, i.e. X is a spacer group, the S-substituents, especially S3, can also be phenoxy or biphenyl, and R?2¿ is equal to Z1 or R1, or is lower alkyl, lower alkenyl, phenyl, or phenyl substituted with lower alkyl or lower alkoxy. The novel compounds may be used as such for modifying the hydrophilic surface for a variety of purposes, such as for chromatographic purposes or for use in electronics, or the compound may be polymerized, optionally using as coreactants known silanes, to form polymers especially well suited for chromatographic purposes.</p> |
