Engineering Molecules for Wavelength Absorption

[eagleone]

I'm interested in engeeniring molecule with specific max. e-m wave apsorption. How to, where from to start ?
eg. Like one used for blocking UV rays (btw do you have formulas of these molecules).

Try a poly conjugated enone. Look up the Woodward rules for UV spectroscopy. He's got all the functional groups laid out in a nice table.

Engineering molecules for specific wavelength absorption can be a complex and challenging task, but with a systematic approach, it can be achieved. The first step is to identify the desired wavelength range for absorption. This will determine the type of molecules that need to be engineered.

Next, research can be done to identify existing molecules or compounds that have similar absorption properties to the desired range. This can serve as a starting point for the engineering process. Additionally, understanding the chemical and physical properties of these molecules can provide valuable insights for the design and synthesis of new molecules.

One approach to engineering molecules for specific wavelength absorption is through molecular design and modification. This involves altering the molecular structure and functional groups to optimize the absorption properties. Computational tools such as molecular modeling and simulations can aid in this process.

Another approach is to use synthetic chemistry techniques to create new molecules with desired properties. This can involve the synthesis of small molecules or the development of polymers with tailored absorption characteristics.

As for the formulas of molecules used for blocking UV rays, there are several compounds that are commonly used for this purpose, such as oxybenzone, avobenzone, and octinoxate. However, the specific formulas may vary depending on the product and manufacturer.

In conclusion, engineering molecules for specific wavelength absorption requires a combination of knowledge, research, and experimentation. It is a continuous process of trial and error, but with persistence and innovation, it can lead to the development of new and effective molecules for various applications.
