B. Luccionihouze et al., SYNTHESIS OF NEW PHOTOCHROMIC COMPOUNDS CONTAINING A SPIN-TRAP OR A SPIN-LABEL, Research of chemical intermediates, 22(5), 1996, pp. 449-457
This paper deals with the synthesis of photochromic compounds containi
ng a spin-trap or a spin-label. Structural assignments are based on NM
R studies and the EPR spectrum of the radical species was recorded. Th
e photochromic performance of the compounds was also investigated and
tile influence of the substituents is discussed.
