In this paper, we study the following quasilinear Choquard equations of the form $$\ -\Delta u+V(x)u-\Delta (|u|^{2\alpha})|u|^{2\alpha-2}u=(|x|^{-\mu}\ast G(u))g(u), \ x \ \in R^N,$$ where $1\geq\alpha>\frac{1}{2}$, $V \in C(\mathbb{R}^N, \mathbb{R})$, $g \in C(\mathbb{R}^N, \ \mathbb{R})$. Distinguished from two situations $\lim\limits_{|x|\rightarrow\infty}V(x)=+\infty$ or $\lim\limits_{|x|\rightarrow\infty}V(x)<+\infty$, we research the existence of nontrivial solutions and a sequence of high energy solutions.
