Q.philodendron plant
I took home my philodendron to repot and over night the leaves turned black on the long vine at the end. What caused this? I had this plant in my window at work and took it home to put in larger pot. When I got up this morning, I had black leaves on the longest vine at the end of it.

Could be the environmental change. Remove damaged leaves and continue to re-pot. Be sure to only go one size up. This link will tell you more about your plant;
