Procedure

A mixture of 5.7 g of 4-dimethylaminocinnamaldehyde, 16.2 g of 1,1-bis(4-dimethylaminophenyl)ethane, 300.0 ml of ethyl alcohol and 6.0 ml of glacial acetic acid was refluxed approximately eighteen hours. After cooling slightly an additional 3.0 g of 1,1-bis(4-dimethylaminophenyl)ethane was added and reflux maintained for an additional four hours. The resulting reaction mixture was cooled to approximately 5° C. and the solid which formed was collected by filtration. The solid was recrystallized from isopropyl alcohol, filtered and dried to obtain 16.3 g of bis{[2,2-bis(4-dimethylaminophenyl)]ethenyl}[2-(4-dimethylaminophenyl)ethenyl]methane (Formula II: R,R1,R3,R4,R9 and R10 =CH3 ; R2, R5 and R11 =H) a yellow solid which melted at 78°-82° C. Significant infrared maxims appeared at 1610 cm-1 (v.s.) and 830 cm-1 (v.s.). An acetone solution of the product spotted onto clay, phenolic resin and organic acid coated papers slowly developed a blue-colored image. Exposure of the spotted papers to bromine vapor increased the speed of color development.
