Fig. 4: Photochromic properties of PMC6 and PMC7.
From: Photochromism of pyridine-substituted merocyanine through reversible C-N bond formation
A, B Photo-switching transition of PMC6 and PMC7 under 660 nm and then 500 nm. Photographs show the color change during the PMC-to-SIZ transition. C, D The photo-induced and thermal-induced recovery kinetic curves of PMC6 (C) and PMC7 (D). E, F Cyclic stability of PMC6 (E) and PMC7 (F) in CH2Cl2 under alternative irradiation (500 nm for 30 s; 660 nm for 30 s).
