NEW MATERIAL:A compound expressed by the formula (X is H or cation capable of forming a salt with sulfonate ion; Y is H or SO3X; n is an integer of 1-8). EXAMPLE:Sodium 1,3,5-hexatriene-1-sulfonate. USE:Useful as a photosensitizer, photosensitive material, etc., having improved photosensitivity and electric conductivity. PREPARATION:The carbon atom at the omega-position of 1-hydroxy-2,4-hexadiene or 1-hydroxy-2,4,6-octatriene as a starting material is initially sulfonated and the hydroxyl group is removed by dehydration reaction to afford the low- molecular weight compound expressed by the formula. The compound, having a large number of carbon atoms and expressed by the formula is obtained by using decane or eicosane, etc., as a starting material, introducing sulfuric acid anhydride into the reaction system and carrying out sulfonation reaction and polyene forming reaction at the same time. |
