trimethyl-6-nitrospiro (SP-1) and 1, 3-Dihydro-1, 3, 3-trimethylspiro
(SP-2), shown in Fig. 1, were purchased from Aldrich and used as
received without further purification. The PS sample was prepared
using anodic etching as reported previously [24]. The etching
conditions involved using a p-type (1–10 Ω cm) silicon and an
etchant of aqueous HF (purity 49%), isopropanol (IPA), and DI water,
1:2:1 by volume at an anodization current density of 50 mA/cm2 for
30 min. Furthermore, 2 102 M spiropyran compounds dissolved
in toluene solution were added on top of the freshly etched PS
samples. All spiro-PS samples were maintained at room temperature
for 5 min to evaporate the solvent before PL measurement was
conducted. PL emissions at room temperature were excited using a
365-nm LED at an excitation intensity of 50 mW/cm2
. A fiber-based
fluorescence spectrometer (USB 4000, Ocean Optics) was used to
record the in situ PL spectra of the samples. Fourier transform
infrared (FTIR) spectra were obtained using an FTIR spectrometer
(Frontier, Perkin Elmer) in transmission mode. Thermal treatment
was applied to the spiro-PS samples using a microwarm plate (TTM-
004, Kitazato).
