Let g be a complex semisimple Lie algebra, b±⊂ g a pair of opposite Borel subalgebras, and r∈ b−⊗ b+ the corresponding solution of the classical Yang–Baxter equations. Let G be the simply–connected Poisson–Lie group corresponding to (g, r), H⊂ B±⊂ G the subgroups with Lie algebras h= b−∩ b+ and b±, and G⁎= B+× H B− the Poisson–Lie group dual of G. G–valued Stokes phenomena were used by Boalch [3],[4] to give a canonical, analytic linearisation of the Poisson–Lie group structure on G⁎. U g–valued Stokes phenomena were used by the first author to construct a twist killing the KZ associator, and therefore give a transcendental construction of the Drinfeld–Jimbo quantum group U ħ g [23]. In the present paper, we show that the former construction can be obtained as semiclassical limit of the latter. Along the way, we also show that the R–matrix of U ħ g is a Stokes matrix for the dynamical KZ equations.
