alkyl group or a halogen group, and each of “a” and “b” independently represents an integer of 0-2, and 1≦a+b≦4. The polyimide and the polyamide are a fluorescent polyimide and a fluorescent polyamide that are easily soluble in organic solvents to the extent that they can be formed into a film by a wet process when making an optical device, that have heat resistance and strength when formed into a film, and that have superior fluorescent characteristics.
