How to remove rows from one dataframe that has matching string in another dataframe - pandas

Question

I have two dataframes. I want to eliminate rows from first dataframe which has matching string in another dataframe. I tried pd.merge() but was unable to get the required results.

For example:

df1 =

              websites
    0    https://www.google.com
    1    https://www.abcd.com
    2    http://en.wikipedia.org

df2 =

            blacklist_website
    0    google
    1    yahoo
    2    wikipedia 

The final dataframe should be like this :

            result
    0    https://www.abcd.com
