Laser-Induced Second Harmonic Generation Decay in a Langmuir- Blodgett Film: Arresting by Polyelectrolyte Templating

Stabilizing Langmuir–Blodgett (LB) films: Laser irradiation accelerates π dimerization of hemicyanine nonlinear optical chromophores in monolayer LB films and causes degradation of their second harmonic generation capability. The metastability of the film is overcome effectively by polyelectrolyte t...

Zusammenfassung:Stabilizing Langmuir–Blodgett (LB) films: Laser irradiation accelerates π dimerization of hemicyanine nonlinear optical chromophores in monolayer LB films and causes degradation of their second harmonic generation capability. The metastability of the film is overcome effectively by polyelectrolyte templating. Nanoscopic characterization (see Figure) of the ultrathin films reveals the impact of the polyelectrolyte.
