im trying to identify photo reactive dye/ compound that changes color when exposed to light, i know of photochromic dyes, unfortunately photochromic dyes undergo a reversible change in appearance. is there a compound that changes in the presenc eof light irreversibly?
Homework Equations
The Attempt at a Solution
Photo reactive dye is a type of dye that undergoes a chemical reaction when exposed to light. This reaction causes a permanent change in the color of the dye.
Photo reactive dye contains molecules that are sensitive to certain wavelengths of light. When these molecules are exposed to light, they undergo a chemical reaction that alters their structure, causing a change in color.
The irreversible change in presence of light refers to the fact that once the photo reactive dye has been exposed to light and undergone its chemical reaction, the change in color cannot be reversed. This is because the molecules of the dye have been permanently altered.
Photo reactive dye has a variety of applications, including in photography, printing, and textile industries. It is also used in certain types of sensors and inks.
Yes, as with any chemical, it is important to handle photo reactive dye with caution and follow proper safety protocols. Some types of photo reactive dye may be harmful if ingested or inhaled, and direct contact with skin should be avoided. It is also important to properly dispose of any unused dye and follow recommended storage guidelines.
