    • (nBu)5 shows a similar behaviour (broad signals at room temperature, better resolved at low temperature). Since the investigation of helical chirality was our first focus, high temperature studies have not been conducted yet. The large number of signals at low temperature may due to aggregation/binding/formation of double helices. For instance protonated dimers are very often observed by mass spectrometry for this family of molecules, but their structure has not been investigated.
