In this paper we study the following family of hypergeometric polynomials:
$y_n(x) = \frac{ (-1)^\rho }{ n! } x^n {}_2 F_0(-n,\rho;-;-\frac{1}{x})$, depending on a parameter $\rho\in\mathbb{N}$.
Differential equations of orders $\rho+1$ and $2$ for these polynomials are given.
A recurrence relation for $y_n$ is derived as well.
Polynomials $y_n$ are Sobolev orthogonal polynomials on the unit circle
with an explicit matrix measure.
