My daughter will be filing for citizenship by derivation. She was under 18 when her father naturalised. She will be applying for a US passport next week. Can she then file for a green card for me?

What about her father...

Her father and I are divorced. She became a u s citizen when her father was sworn in and she was under 18 and was a legal resident last year march.

Yes, she can petiton for you. You qualify as an IR.
