Graphical Abstract
Get turned on: Fluorescent photochromic organic nanoparticles (FPONs) of 1 (see picture) show a strongly enhanced fluorescence emission with increasing concentration and bistable photochromism. High-contrast on/off fluorescence switching has been successfully implemented in size-tuned FPONs of 1 and also in a photo-rewritable polymer film highly loaded with 1.

- 20Preparation of FPONs: All suspensions of FPONs were prepared by the reprecipitation method from THF solution with distilled water. Volume fractions of THF and water were adjusted to 20 and 80 %, respectively. See ref. [19] for details.
- 21Fluorescence quantum yields: The fluorescence quantum yields (ΦF) were relatively calculated using 9,10-diphenylanthracene (DPA) in benzene (see ref. [22]) and in PMMA (see refs. [29,30]) as a standard reference (1×10−3 m, ΦF=83 %). Through this method, the ΦF values of FPONs of 1 a were determined as 3.2, 5.1, 4.1, and 3.4 % (
=485, 489, 491, and 493 nm, 
=371, 374, 378, and 382 nm) in the 1 a form, and as 0.20, 0.09, 0.04, and 0.02 % in the PSS with increasing FPON size of 40±10, 125±25, 200±50, and 275±75 nm, respectively. It is reasonably considered that the slight reduction of the ΦF values in 200±50 and 275±75 nm FPONs of 1 a results from the highly increased virtual absorbance values by increased light scattering. In fact, the extent of the apparent absorbance of the FPONs of 1 a at the excitation wavelength, that is at 360 nm, was almost linearly proportional to their suspension concentrations in spite of the inverse proportional relationship between the mean radius and the surface-to-volume ratio of the FPONs.

- 26Determination of the conformational population and conversion rate: A 1H NMR spectroscopic study (2×10−4 m of CDCl3 solution, 22 °C, 300 MHz) on the 1 a form showed that the parallel and antiparallel conformations were equally populated in solution, as evident by there only being two singlet resonances at δ=1.98 and 1.91 ppm without any splitting. These signals were assigned as the methyl protons at the 2-positions of the thiophene rings of the 1 a form (see ref. [27]). The conversion rate of about 35 % in the PSS was calculated by the integrated ratio between the singlet peaks of methyl protons in the 1 a form and those in the 1 b form, which newly appeared at δ=2.15 and 2.11 ppm.
