Photo-Reversible Nanoscale Surface Relief Grating Patterns on Azobenzene-Containing Polymer Thin Film
Idea: combine azobenzene moieties with “bulky” side chain polyamidoamine (PAMAM) dendritic wedge diol
expect to decrease azobenzene aggregation => improve polymer film stability/photoeffectiveness
trans-azobenzene
stable state
cis-azobenzene
excited state
Photo-Responsive Side Chain Dendritic Polyesters (SCDPE)
Photo-mask
10 µm spacing
Polymer film spin coated on quartz substrate
UV exposure
