Dimerization of exhaustively substitute p-nitrosophenols was studied by H-1 and C-13 NMR, UV, and IR spectroscopy. The results showed that these compounds in crystal exist as strong dimers having a diazene N,N'-dioxide structure. An equilibrium between the dimeric and monomeric forms of nitrosophenols in solution was revealed for the first time.

In chemical structure of a fulgide type photochromic compound having the following general formula; ##STR1## introduction of electron donative groups into its heteroaromatic structure is effective in improving the long wave length sensitivity without any lowering in its thermal stability. Thanks to such combined functional properties, the products are advantageously used for optical recording media, copying media, printing media, optical filters and display materials.
