They are probably infected with wilt. disease, which may be fungal (Fusarium or Verticillium wilts) or bacterial. All of these will affect any plant in the nightshade family, which includes tomatoes, peppers and eggplants.

Generally, there is no cure once your plants become affected with wilt. In most cases the infected plants should be disposed of and the beds solarized to prevent future issues.
