An Unprecedented Planar π-conjugated [B2P5] Group with Ultra-large Birefringence and Nonlinearity: an ab-initio Study

Abstract

Searching for new NLO-active (nonlinear optical active) units would greatly promote the developments of NLO materials. Herein, we theoretically investigate a newly reported [B2P5] group which is consisted of two corner-sharing [BP3] trigonal planar units. Attributed to the coplanar π-conjugated configutation and the unique connection modes, [B2P5] group can achieve both the largest birefringence (△n ~ 0.68) and nonlinearity (d15 ~ 57.14 pm/V) among all the planar NLO-active groups, and thus would inspire a new direction for new classes of NLO materials.
