Abstract
The greatest problem in creating organic molecular magnets seems to be to find systems in which there is a strong exchange interaction but which are also chemically and thermally stable. This paper discusses one possible solution to this problem, the use of ‘strain protection’, and the synthesis of stable strain-protected pi biradical, trioxytriangulene. This is the first representative of a new, unexplored family of pi biradicals, the non-Kekulé polynuclear aromatics.
