Optically active polymer containing P‐stereogenic bisphosphine as a repeating unit in the main was successfully synthesized. A coordinated borane on the phosphorus atom could be completely removed by an organic base under mild condition, and the successive reaction with Pd afforded the corresponding polymer complex. The chirality of P‐stereogenic centers was transferred to the m‐phenylene‐ethynylene linkers by complexation because of the prohibition of the rotary motion of the bisphosphine‐Pd unit.
