The study of molecules that self-assemble through noncovalent <br>interactions is one of the most attractive topics in supramolecular <br>chemistry. The use of short peptides or modified nucleotides as building<br> blocks for the aggregates is particularly intriguing because these are <br>very easy to synthesize; moreover, subtle changes in the chemical <br>structure of such building blocks may drastically affect the properties <br>of the aggregates. The ability of peptide nucleic acids (PNA) to <br>aggregate has been very little explored, despite its practical <br>applications. In this work we investigated the self-assembling <br>properties of a PNA dimer, conjugated at the N-terminus to a <br>fluorenylmethoxycarbonyl group. This PNA dimer forms nano-aggregates at <br>low concentration in CHCl<sub>3</sub> /CH<sub>3</sub> OH mixtures. The <br>aggregates retain very interesting fluorescent properties (high quantum <br>yield in the visible region with lifetimes on the nanosecond scale), <br>which make them promising materials for applications in optoelectronics.
