研究了顺磁性全有机手性近晶液晶的二阶非线性光学性质。在铁电手性近晶C（SmC*）相的相位匹配条件下，可以清楚地观察到二次谐波产生（SHG）。有效的二阶NLO常数被评估为4.8 × 10（-4）pm/V，比已知为标准NLO材料的石英小3个数量级。(C)2010日本应用物理学会
Second-order nonlinear optical (NLO) properties of a paramagnetic all-organic chiral smectic liquid crystal have been studied. Second-harmonic generation (SHG) was clearly observed under a phase-matching condition in the ferroelectric chiral smectic C (SmC*) phase. The effective second-order NLO constant was evaluated to be 4.8 x 10(-4) pm/V, 3 orders of magnitude smaller than that of quartz known as a standard NLO material.
