Abstract
In this investigation we introduce, by making use of q-derivative operator, a new subclass which are an extension of some well-known subclasses of bi-univalent functions. Also, we give the upper bounds for the coecients ja2j and ja3j for the functions belonging to this new subclass and its subclasses.
