Its aggregation processes depend on the protonation of both the spermine units and central core nitrogen atoms. Therefore, the time duration of pH titrations and/or the direct protonation of a specific site allow for choosing the desired aggregation state of the system. † Electronic supplementary information (ESI) available: All synthetic compounds were characterised by 1 H NMR, APT, 1D-zTOCSY, ESI-MS and UV-vis spectroscopy.
