| Therefore, we have attempted to create a simple, reversible photochromic metal-ion chelator that can be analyzed quantitatively. |
| Demand for photochromic and polarized lenses is also rising beyond overall market demand. |
| Faulkner wore jeans faded at the knees, a broad hat, and photochromic sunglasses. |
| With its photochemical cycle, bR represents a reversible photochromic system in addition to its charge translocation property. |
| Also, photochromic substances can be restored to their original state after being in the dark for a period of time. |
| The photochromic dyes cyclize smoothly in polar organic solvents and water upon UV light irradiation while undergo fading under visible light. |
