abstract = {<p style="text-align: justify;">In this paper, we are dedicated to studying the following singularly
Choquard equation $$−ε^2∆u + V (x)u = ε^{−α} [I_α ∗ F(u)] f(u), \ x ∈ \mathbb{R}^ 2,$$ where $V (x)$ is a continuous real function on $\mathbb{R}^2,$ $I_α : \mathbb{R}^2 → \mathbb{R}$ is the Riesz
potential, and $F$ is the primitive function of nonlinearity $f$ which has critical
exponential growth. Using the Trudinger-Moser inequality and some delicate
estimates, we show that the above problem admits at least one semiclassical
ground state solution, for $ε &gt; 0$ small provided that $V (x)$ is periodic in $x$ or
asymptotically linear as $|x| → ∞.$ In particular, a precise and fine lower bound
of $\frac{f(t)}{e^{\beta_0 t^2}}$ near infinity is introduced in this paper.</p>},
