Oligomeric compounds of a perfectly defined length, polydispersity 1.0, are highly desirable for a variety of applications. We were interested in using them to link peptidomimetics providing bi- and multivalent molecules that might potentially bind with protein targets. 1 We needed linkers with some intrinsic water solubility, that did not have charged functional groups, but that were able to span dimensions from about 10 Å to around 50 Å. They might also incorporate ...
