Ligand exchange of PtSA@CdSe with CdBr2 and MUA. MUA
(232 mg) and KOH (236 mg) were dissolved in H2O (4.38 mL). A toluene
dispersion of PtSA@CdSe (3 mM of Se, 1000 µL) was centrifuged. The
sediment was rinsed with a toluene/anhydrous MeCN/DMSO
(45:45:10) solution of CdBr2·4H2O (60 mM, 1000 µL) three times and
with toluene/anhydrous MeCN (1:1, 1000 µL) twice by redispersion and
centrifugation. The sediment was dispersed in the aqueous solution of
MUA and KOH (1000 µL). The dispersion was stirred at 20 °C for 1 h.
The solids were collected by centrifugation and rinsed with MeOH
(1000 µL) twice by redispersion and centrifugation. The sediment was
redispersed in H2O (1000 µL) and subjected to dispersion-state analyses and photocatalysis. For powder-state analyses, the solids were
