1 (0.164 g, 0.220 mmol), 3 (0.209 g, 0.220 mmol) and 15 mg of
(PPh3)4Pd(0) were added 2 M aqueous potassium carbonate (4 mL,
N2purged) and the phase transfer catalyst, Aliquat 336 in toluene (8
mL, N2purged). The reaction mixture was heated at 85 °C for 24 h,
excess bromobenzene in 1 mL toluene (N2purged) was added as an
end capper, and further reacted for another 12 h. The reaction mixture
was cooled down to room temperature and precipitated into vigorously
stirred methanol (200 mL). The polymer fibers were collected by
filtration and washed for 2 days in a Soxhlet apparatus with acetone to
remove oligomers and catalyst residues. The neutral precursor polymer
was obtained after drying in vacuo. Yield: 66% (186 mg). Mn= 25 000 g
mol−1(Mw/Mn= 1.26). The quaternization of the neutral precursor was
followed with trimethylamine.[24] Condensed trimethylamine (3–5 mL)
was added dropwise to a solution of the neutral precursor (100 mg) in
10 mL THF at –78 °C. The mixture was allowed to warm up to room
temperature overnight. The precipitate was re-dissolved by addition of
methanol and 2 mL trimethylamine was added at –78 °C. The resulting
mixture was stirred for additional 24 h at room temperature. After
removal of the solvent under reduced pressure, acetone was added
to precipitate the charged polymer (P1). The precipitated P1 was then
collected and dried under vacuum. Yield: 85% (93 mg). 1H NMR

Potassium Ion Assay Protocol: All PL experiments were performed
in 20 mM Tris-HCl buffer (pH = 7.4) containing 100 mM NaCl as a
salt. Stock solutions (10−6 M) of 3 kinds of potassium aptamers were
prepared in deionized water. 20 μL of the aptamer stock solution was
diluted to 2 mL buffer, and the resulting solution was incubated at 60 °C
for 30 min with and without K+ ions. The annealed solution was cooled
down to room temperature for 1 h and the PL spectra were measured
by exciting 6-FAM at 490 nm. Then, P1 was added to the above solution
and PL spectra were measured again by exciting the polymer at 390 nm.
The same protocol was repeated in the presence of NaCl, CaCl2, LiCl,
MgCl2, NH4Cl, CuCl2, AgCl, ZnCl2, and AlCl3 (20 mM, respectively)
instead of KCl for the selectivity evaluation.
