Abstract
In the last decades, chemists have developed methods to synthesize helical molecular architectures using a combination of covalent and non-covalent interactions. Very recently, the new class of completely covalent, one-handed helical ladder polymers has vigorously emerged. Such polymers can be rationally and programmably obtained through an approach guided by the principles of chirality-assisted-synthesis (CAS) and making use synergically of two disciplines that have so far rarely interacted: non-planar chiral π-conjugated synthons and ladder polymer chemistry. The precise programmability of the 3D structure and new mechanical and chiroptical properties will lead to potential applications in areas such as enantiorecognition, catalysis, spintronics and chiral-related optoelectronics. This minireview examines the emerging field of one-handed helical ladder polymers, analyzing their synthesis, applications, and limitations.
