Layer-By-Layer Deposition and Ordering of Low-Molecular-Weight Dye Molecules for Second-Order Nonlinear Optics

A combination of electrostatic interactions and covalent bonding is used to form films with low‐molecular‐weight chromophores by a layer‐by‐layer deposition process. Using a common, commercially available red dye, this deposition process results in noncentrosymmetric films (see scheme) that exhibit...

Description
Summary:A combination of electrostatic interactions and covalent bonding is used to form films with low‐molecular‐weight chromophores by a layer‐by‐layer deposition process. Using a common, commercially available red dye, this deposition process results in noncentrosymmetric films (see scheme) that exhibit second‐harmonic generation (red→green), with χ(2) values as large as 11.3×10−9 esu, that is, six times that of quartz.
