The Spectroscopic and Orphological Characterizations of the Polymers and PNs
(A) Absorbance (dashed curve) and PL spectra (solid curve) of P1 (red) and P2 (green) in a solution of MeCN:benzene = 1:1. λexc = 350 nm.
(B) Absorbance (dashed curve) and PL spectra (solid curve) of PNs-1 (blue) and PNs-2 (red) in aqueous solution. λexc = 350 nm.
(C) AIE effect of P2. Plots of I/I0 vs water fractions in THF/water mixtures (10 μM), where I0 and I are the PL intensities in pure THF and THF/water mixtures, respectively. Inset: Photographs of P2 in THF/water mixtures (0, 90%) taken under 365 nm UV lamp.
(D) High-resolution TEM image of 9 nm PNs-2. Scale bar, 10 nm. Data are represented as mean ± TEM.
