Hydrogen-Bonding Fabrication of NLO Langmuir−Blodgett Films with Nontraditional Molecular Architecture and Unique Thermal Stability

Abstract

The SHG active nontraditional LB architectures of monolayers and multilayers were fabricated based on molecular interactions of hydrogen bonding. After photopolymerization of the diacetylene groups, the SHG thermal stability of the obtained LB films could be improved substantially and all the polymerized films exhibited unique SHG thermal rebounding phenomena.
