The key purpose of this paper is to investigate the Bohr radiusfor several subclasses of analytic functions with negative coefficients. Ourinvestigation with the Bohr radius correlates with the classes of generalized Janowski type functions. Under this novel strategy, we developBohr’s phenomenon for a generalized class associated with q-functionshaving q ∈ (0, 1). In the applications viewpoint, our consequences haveshown the applicability in the class inaugurated by Bessel functions.
