EXAMPLE - 3 mmole of Unsubstituted 5,6-dicyanoazulene or 1,3-disubstituted 5,6-dicyanoazulenes, 1 mmole of 4,5-dipentoxycarbonylphthalonitrile and 1.4 mmole of dry zinc acetate were suspended in 50 ml of dry 1-pentanol. The mixture was heated under inert gas and stirred at 145 degrees C. 2 mmole of 1,8-Diazabicyclo(5.4.0)undec-7-ene was added and heated for 24 hours at 145 degrees C. The cooled reaction mixture was added to methanol, and the precipitate was filtered. The azulenocyanine analogue compounds were dissolved in chloroform under addition of a small amount of dimethylformamide and isolated to give 25% of black colored azulenocyanine analogue diesters.
