A series of linear covalent assemblies of dendrimers with conjugated backbones were synthesized by means of an iterative divergent and convergent method in which copper-catalyzed acetylene-azide cycloaddition reactions were used to form flexible linkages. UV-vis and fluorescence spectra indicate that dendrimeric assemblies have a strong propensity to adopt folded conformations in which conjugated backbones adopt planar conformations. The folded conformation is stabilized by strong attractive van der Waals and dipole-dipole interactions between the dendrimers.
