(a) Changes in the fluorescence decay profiles of the PCP-TPy1, PCP-TPy1/EsY (200:1), PCP-TPy1/NiR (200:1) and PCP-TPy1/EsY/NiR (2000:10:10) in THF/Water (1:9; v/v), (b) Changes in the fluorescence decay profiles of the Rp,Rp-PCP-TPy1, Rp,Rp-PCP-TPy1/EsY (200:1), Rp,Rp-PCP-TPy1/NiR (200:1) and Rp,Rp-PCP-TPy1/EsY/NiR (2000:10:10) in THF/Water (1:9; v/v).
