Photochromic metal organic frameworks for inkless and erasable printing |
| abstract |
The present invention disclose photochromic metal organic frameworks (MOFs) containing photochromic 1,4,5,8-naphthalenediimide (NDI) core and metal ions selected from Mg, Ca or Sr. The developed MOFs find application in inkless and erasable printing wherein they retain the photogenerated colour for a prolonged period of time so that the printed content remains legible/readable for reasonable time. |
