Abstract:

The geometrical structures, relative stabilities and nonlinear optical properties of superalkali-based electrides Li3@calix[4]pyrrole and Li3O@calix[4]pyrrole were studied in theory. Four and two isomers were identified for Li3@calix[4]pyrrole and Li3O@calix[4]pyrrole, respectively. The results show that, replacing alkali metal with superalkalis brings larger NLO responses to the electrides. In addition, the Li3 and Li3O molecules are ionized to a greater degree when they are parallel to the plane composed by four N atoms of the calix[4]pyrrole complexant. As a result, such structures exhibit larger first hyperpolarizabilities(β0) than the other isomers.
