Participants

Reaction Conditions

Reaction Steps

2 g (5 mmol) of N-(5-hydroxypentyl)perylene-3,4-dicarboximide from Example 7, 1. were dissolved in 60 ml of pyridine under nitrogen, with heating at 80° C., and the solution was admixed dropwise at this temperature with a solution of 0.97 ml (10 mmol) of methacryloyl chloride in 30 ml of anhydrous dioxane. Stirring was continued at 80° C. for a further 1.5 h, the solvent was removed by distillation, the residue was taken up in 30 ml of chloroform, a filtration was conducted, the filtrate was admixed with 100 ml of hexane and the precipitated product was isolated by filtration. Chromatographic purification on a short silica gel column using methylene chloride as eluent gave 1.6 g (70%) of the desired product as a brownish red powder.
