Within the framework of the perturbative QCD approach, we study the branching ratios of the two-body charmed decays B-(s) -> a(1)(b(1))D-(s), a(1)(b(1))D-(s)*, which, including Cabibbo-Kobayashi-Maskawa, allowed and suppressed decays. Our calculations are consistent with the currently available data and the experimental upper limits. Certainly, many of these predicted channels have not been measured by experiments and can be confronted with the future experimental data. We also discuss the polarization factions of the decays B-(s) -> a(1)(b(1))D-(s)*, some of which are sensitive to the distinct Gegenbauer moments of the wave functions and the decay constants of mesons a(1) and b(1).
