Phosphorescence is ubiquitous in heavy atom-containing organic phosphors, which attracts considerable attention in optoelectronics and bioelectronics. However, heavy atom-free organic materials with ...

It's an old organic chemistry tenet that conjugated polyenes, with their alternating double and single bonds, are more stable than their unconjugated isomers. An abundance of lab experiments and ...

From their first organic chemistry course, students learn that the more substituted an alkane, the weaker the remaining C-H bonds, and the more stable the molecule's corresponding radical. The reason ...

THE recent statement by Kreevoy and Eyring 1, based on theoretical considerations, that the hyperconjugation energy is approximately proportional to the number of α-hydrogen atoms, is supported by an ...
