Is there a formal or semantic difference between these sentences?

1. This sentence is false.
2. The sentence containing these words is false.

EDIT: It seems the question is too ambiguous to be answered. I don't know how to make it less so. Perhaps someone could add an edit. I wnat to say the two sentences are equivalent but first I want to check my reasoning as I'm not a logician. If someone stated these sentences are equivalent what would be your response?
