Abstract | The interaction of conjugated polyelectrolyte, PPE-SO3
−
, with platinum(II) complexes,
[Pt(tpy)(C≡CC6H4CH2NMe3-4)](OTf)2 (1) and [Pt(tpy)(C≡C–CH2NMe3)](OTf)2 (2), has been studied
by UV–vis, and steady-state and time-resolved emission spectroscopy. A unique FRET from PPESO3
−
to the aggregated complex 1on the polymer chain with PtfflfflfflPt interactionhas been demonstrated,
resulting in the growth of triplet metal-metal-to-ligand charge transfer (3MMLCT) emission in the nearinfrared (NIR) region. This two-component ensemble has been employed in a “proof-of-principle”
concept for the sensitive and selective label-free detection of HSA by the emission spectral changes in
the visible and NIR region, which have been ascribed to the disassembly of the polymer-metal complex
aggregates upon the binding of PPE-SO3
−
to HSA, leading to the decrease in FRET. The ensemble is
found to have high selectivity towards HSA over a number of polyelectrolytes, proteins and small amino
acids. This has been suggested to be a result of the extra stabilization gained from the PtfflfflfflPt and π–π
interactions in addition to the electrostatic and hydrophobic interactions found in the polymer-metal
complex aggregates. [1]
