We consider the (finite-dimensional) restricted quantum group U‾qsℓ(2) at q=i. We show that U‾isℓ(2) does not allow for a universal R-matrix, even though U⊗V≅V⊗U holds for all finite-dimensional representations U,V of U‾isℓ(2). We then give an explicit coassociator Φ and a universal R-matrix R such that U‾isℓ(2) becomes a quasi-triangular quasi-Hopf algebra. Our construction is motivated by the two-dimensional chiral conformal field theory of symplectic fermions with central charge c=−2. There, a braided monoidal category, SF, has been computed from the factorisation and monodromy properties of conformal blocks, and we prove that Rep(U‾isℓ(2),Φ,R) is braided monoidally equivalent to SF.
