These EVs'combined effort restricts the flexibility of the compounds and thus could reflect the best conformation with which the ligands interact with the receptor.

扭曲构象为较好的发光构象。分子受激后,平面构象可经旋转松弛到扭曲构象。
The twisted conformation was favorable for luminescence, and the excited coplanar molecule could relax to the twisted conformation.
