- n is an integer greater than 1;
- X is a phenyl moiety substituted with 2-4 halo groups or 2-4 C1-C4 trihaloalkyl groups;
- each D, independently, is a benzodithiophene moiety, a carbazole moiety, a fluorene moiety, a cyclopentadithiophene moiety, or a silacyclopentadithiophene moiety;
- A is a cyclopentadithiazole moiety, a benzothiadiazole moiety, a thiadiazoloquinoxaline moiety, a benzoisothiazole moiety, a benzothiazole moiety, a thienothiophene moiety, a tetrahydroisoindole moiety, a thiazole moiety, a thiazolothiazole moiety, a naphthothiadiazole moiety, a thienopyrazine moiety, an oxazole moiety, an imidazole moiety, a pyrimidine moiety, a benzoxazole moiety, a benzimidazole moiety, a pyridopyrazine moiety, a pyrazinopyridazine moiety, a pyrazinoquinoxaline moiety, a thiadiazolopyridine moiety, a thiadiazolopyridazine moiety, a benzooxadiazole moiety, an oxadiazolopyridine moiety, an oxadiazolopyridazine moiety, a benzoselenadiazole moiety, a benzobisoxazole moiety, a thienothiadiazole moiety, a thienopyrroledione moiety, a tetrazine moiety, a pyrrolopyrroledione moiety, a thiophene moiety, a selenophene moiety, a thiadiazole moiety, a quinoxaline moiety, a benzotriazole moiety, or a furan moiety;
- each T, independently, is a thienothiophene moiety, a thiazole moiety, a thiophene moiety, a selenophene moiety, a thiadiazole moiety, or a furan moiety;
- and
- the article is configured as a photovoltaic cell.
