Characterization of FSNPs. (a) DLS data and (b) TEM image of the FSNPs selected from the combinatorial library (⋆, Figure 2b). The hydrodynamic size of the FSNPs, obtained by DLS, is 670 ± 43 nm, and TEM image reveals that FSNPs are homogeneous spherical nanoparticles. (c) Photograph of free MPS-PPV and the 670 nm sized FSNP solution with UV light irradiation (excitation = 365 nm). Comparison of (d) emission and (e) absorption spectrum of free MPS-PPV and the 670 nm sized FSNP. (f) Photophysical properties of free MPS-PPV and the 670 nm sized FSNP. All properties were calculated based on the repeating unit of MPS-PPV. Dramatically enhanced fluorescence is observed with the 670 nm sized FSNPs which exhibits ca. 10-fold higher emission and ca. 6.8-fold higher absorption than free MPS-PPV.
