摘要

~0.4) exhibits the enhancement of a single component of γ, γ_(inter) (γ_(intra)), at the intermediate y _(inter) (y _(intra)) region (~0.3–0.4), and (ii) in contrast to conventional diradical systems, the system exhibits a further enhancement of both components of γ (γ_(intra) and γ_(inter)) at the region where y _(intra) ~ y _(inter) with small values (≤~0.3). The obtained relationships are verified by using ab initio quantum chemical calculations of the realistic tertraradical models of a 4,4′-bis(1,2,3,5-dithiazdiazolyl) (BDTDA) dimer and a disilene dimer. The present results are expected to pioneer an alternative class of two-dimensional multiradical NLO systems, which potentially cause further enhancement of γ as compared with conventional intermediate diradical NLO systems.]]>
