A poly(dT) oligomer can serve as the string on which synthetic hairpins possessing poly(dA) and poly(dT) arms connected by a hydrophobic perylene diimide linker are assembled like beads on a string. The synthetic hairpins form head-to-head dimers and trimers, respectively, in the absence of the poly(dT) string and in the presence of a string with inverted polarity at mid-strand. However, they assemble in cooperative head-to-tail fashion on normal poly(dT) oligomers.
