摘要：

The title compound, C23H18Br2O5, is one of a series of soluble precursors to electroluminescent conjugated polymers and helical structures. The geometries of the rings are within normal limits, as are those of the ethyl esters. There are few close contacts within the molecule, leading one to rationalize that the overall geometry arises from pure steric interactions without any attractive forces such as hydrogen bonding.
