Patent ID: 8283469

Claim:
A perylene diimide derivative of a general formula: wherein m and n are respectively selected from integers 1-5 and independent to each other, and wherein R 1 , R 2 , R 3 and R 4 are respectively selected from an electron withdrawing group consisting of halogens, and a cyanogen group, and wherein R 5 -R 9 and R 10 -R 14 , which are respectively at two ends of the molecule of the perylene diimide derivative, are independent to each other, and wherein one of R 5 -R 9 is selected from a fluorine group, and wherein another one of R 5 -R 9 is selected from a C 1 -C 20 fluorinated alkyl group or a C 1 C 20 perfluorinated alkyl group, and wherein the rest of R 5 -R 9 are hydrogens, and wherein one of R 10 -R 14 is selected from a fluorine group, and wherein another one of R 10 -R 14 is selected from C 1 -C 20 fluorinated alkyl group or C 1 -C 20 perfluorinated alkyl group, and wherein the rest of R 10 -R 14 are hydrogens, and wherein the perylene diimide derivative is soluble and has air-stability.
