Characterization of co-assembled system from 1•2•3. a Schematic representation for the triplet energy transfer of the ternary complex 1•2•3 in aqueous medium. b Transmission electron microscopic image recorded on a copper grid by drop-casting complex 1•20.1•31.1 [1: 5.00 × 10−5 M in water/MeOH (90:10, v/v)]. Scale bar: 500 nm. c Emission spectra and d emission decay traces for the ternary complex 1•2x•3(1 + x) [1: 5.00 × 10−5 M in water/MeOH (90:10, v/v), x varies from 0 to 0.1]. For d, the emission wavelength is chosen at 525 nm, considering that 2•3 displays negligible emission at the selected wavelength. Inset of d: emission color images of 1•3 (left) and 1•20.03•31.03 (right) under 365 nm ultraviolet lamp. e Relationship of the energy-transfer rate constant (kET) value in the ternary complex 1•20.1•3(1.1+x) and the excessive amount of 3 [1: 5.00 × 10−5 M in water/MeOH (90:10, v/v), x varies from 0 to 0.4]
