Abstract

Abstract: Ladderphanes are a new type of duplex polymers. The two strands are connected by a variety of linkers via covalent bonds or hydrogen bonds. The backbones for the two polymeric strands can be symmetrical and complementary. In this Report, recent advances on the design, synthesis and properties of ladderphanes and related polymers are reviewed. Certain ladderphanes, whether symmetrical or unsymmetrical, can readily assemble on HOPG surface to exhibit highly ordered patterns. The linkers in these polymers are aligned coherently so that strong interactions between them can take place as revealed by a number of interesting photophysical properties. Graphical abstract:
