A phenanthrene co-guest helps crystalline sponges reveal 3D structures of small, low-polarity molecules
来源: Phys.org - latest science and technology news stories · 发布于
Adding phenanthrene as a co-guest let the second-generation crystalline sponge (2G-CS) method determine X-ray structures for 24 of 30 small, low-polarity C₁₅ molecules, mostly sesquiterpenoids. Under standard conditions, none of the 30 gave guest-containing crystals. Eleven of th
Adding phenanthrene as a co-guest let the second-generation crystalline sponge (2G-CS) method determine X-ray structures for 24 of 30 small, low-polarity C₁₅ molecules, mostly sesquiterpenoids. Under standard conditions, none of the 30 gave guest-containing crystals. Eleven of the 24 structures had not been reported before, including that of the liquid hydrocarbon longifolene.
A chiral version of the cage gave the absolute configurations of five compounds.

Researchers highlight ferroptosis's dual roles in plant immunity
When plants encounter pathogens, they can defend themselves by rapidly killing infected cells to restrict pathogen spread. This immune response, known as the hypersensitive response (HR), was first described in 1915. However, the molecular mechanism underlying HR cell death remai
