phosphonic acids

Since the work of Schwarzenbach in 1949, phosphonic acids are known as effective chelating agents.

Phosphonates are highly water-soluble while the phosphonic acids are only sparingly soluble.

Franz took over the research in 1969 and incorrectly hypothesized that the phosphonic acids acted as proherbicides that were metabolized to active compounds rather than herbicides.

Although the term is almost always applied to organic compounds, acyl groups can in principle be derived from other types of acids such as sulfonic acids, phosphonic acids.

Going clockwise from the top: Thionyl chloride will transform sulfinic acids into sulfinyl chlorides and phosphonic acids into phosphoryl chlorides.

He currently studies dyes for nonlinear optical studies including two-photon absorption and optical limiting, surface modification using phosphonic acids, and materials for charge transport in solar cells and field-effect transistors.

The CM meteorite Murchison has over 70 extraterrestrial amino acids and other compounds including carboxylic acids, hydroxy carboxylic acids, sulphonic and phosphonic acids, aliphatic, aromatic and polar hydrocarbons, fullerenes, heterocycles, carbonyl compounds, alcohols, amines and amides.
