Controllable photophysical properties and self-assembly of siloxane-poly(amidoamine) dendrimers

Siloxane–poly(amidoamine) dendrimers (Si–PAMAM) can emit strong luminescence due to the aggregation of carbonyl groups, induced by N → Si coordination bonds. So the fluorescence of Si–PAMAM could be adjusted by solvents, H⁺, metal ions, and dendrimer structures. Micron-sized tube were observed in water–methanol due to the self-assembly of Si–PAMAM.
