| Popis: | Octameric near-IR dye nanoclusters are produced by complexation of potassium cations with a phthalocyanine-guanosine conjugate. The combination of hydrogen-bonding, K+ coordination, π-π stacking and steric interactions between the chiral side groups is responsible for defining a specific helical chromophore arrangement in the clusters, which display high stability and maintain their supramolecular identity onto substrates Financial support from MINECO, Spain (CTQ‐2014‐52869‐P, T.T.; CTQ2014‐57729‐P, D. G.‐R.), the Comunidad de Madrid (S2013/MIT‐2841 FOTOCARBON, T.T.), and the European Research Council (ERC‐StG 279548, D. G.‐R.) is acknowledged |
