Usingofannihilation data collected at a center-of-mass energywith the BESIII detector operating at the BEPCII collider, we search for the semileptonicdecays into aaxial-vector meson for the first time. No significant signal is observed for either charge combination. The upper limits on the product branching fractions are BD0→b1(1235)-e+νe·Bb1(1235)-→ωπ-<1.12×10-4 and BD+→b1(1235)0e+νe·Bb1(1235)0→ωπ0<1.75×10-4 at the 90% confidence level.
