Using 2.93 fb-1 of e(+)e(-) data collected at a center-of-mass energy root s = 3.773 GeV with the BESIII detector operating at the BEPCII collider, we search for the semileptonic D0(+) decays into a b(1)(1235)(-(0)) axial-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+ve. Bb1(1235)-->omega pi- < 1.12 x 10(-4) and BD+-> b1(1235)0e+ve center dot B-b1(1235)0 ->omega pi 0 < 1.75 x 10(-4) at the 90% confidence level.
