Chemists Create Oddly-Shaped Molecules That Stay Stable in Air
Researchers have synthesized a new class of contorted phosphorus-containing compounds that resist degradation from air and moisture—a major practical advantage for industrial chemistry. The discovery could accelerate development of materials for electronics and catalysis, where molecular instability currently limits commercial viability.
Originaltitel: Contorting the hetero phosphaquinoid: synthesis and electronic insights into a non-planar, ferrocenyl phosphaquinoid
<p>We report a highly contorted phosphaquinoid by substituting one of the exocyclic C C bonds of an anthraquinodimethane unit with a phosphaalkene unit (–C P-Mes*, Mes* = 2,4,6-tri-tbutylbenzene) and end-capping the opposite terminus with ‘ C(Fc)Ph’. Both isomers (E,Z) exhibit butterfly-like distortion of the anthracene core and demonstrate remarkable stability towards air and moisture.</p>
