The article reports according to the chemist at Japan's Mie University, Katsuyuki Hirai, Hideo Tomioka, and coworkers that a triplet diphenylcarbene with unprecedented stability, an organic diradical with unpaired electrons, can survive 24 hours in solution by adding large yet unreactive substituents to the molecule's ortho positions. After a day in solution at room temperature, traces of the triplet carbene were still detectable spectroscopically. The researchers attribute the molecule's remarkable stability to a perpendicular arrangement of the CF3 groups.

Presents updates related to the chemical industry in terms of technology and environment as of August 15, 2001. Date set by the United States Environmental Protection Agency on chemical producers to comply with the leak detection and repair standards for polyethylene terephthalate units; Isolation made by the scientists at Mie University in Tsu, Japan, on a relatively stable carbene.

Reports on Japanese chemists' discovery of a carbene derivative in the triplet state that is significantly more stable than previously observed triplet carbenes. Possible direction into organic ferromagnetic materials.
