Electrochemical and theoretical investigations over triple-quadruple-, quintuple-, and sextuple-decker sandwich-type compounds {[(Pc*)Sm][(Pc*)Cd (Pc*) ][Sm(Pc*)]} ( = 0-3) elucidate successive π-π interaction-linked extension in the perpendicular direction of the phthalocyanine plane along with increasing the stacked tetrapyrrole number, significantly improving the nonlinear optical properties including effective imaginary third order molecular hyperpolarizability and optical limiting threshold.
对三重 - 四重、五重和六重夹心型化合物{[(Pc*)Sm][(Pc*)Cd(Pc*)][Sm(Pc*)]}（ = 0 - 3）进行的电化学和理论研究表明，随着堆叠四吡咯数量的增加，酞菁平面垂直方向上通过连续的π - π相互作用连接的延伸显著改善了非线性光学性质，包括有效的虚数三阶分子超极化率和光学限幅阈值。
