A series of supramolecular complexes between a water-soluble achiral polythiophene derivative (PT-1) and various nucleotides has been prepared. It was found that upon the introduction of adenosine diphosphate (ADP), adenosine triphosphate (ATP), and uridine triphosphate (UTP) into aqueous solutions of achiral PT-1, which has a random-coiled conformation, chiral supramolecular pi-stacked aggregates of PT-1 can be constructed. These complexes exhibit an unique split-type induced circular…

Thermo- and solvent-responsive polymer complex created from supramolecular complexation between a helix-forming polysaccharide and a cationic polythiophene.
TLDR
A new modified polysaccharide (Cur-oeg) is designed to form a "loose" macromolecular complex with a conjugated polymer (CP) that allows structural changes in response to external stimuli, and it is shown that the induced thermoresponsiveness is associated with structural rearrangement of the helical conformation of PT1 in the complex.

TLDR
A new strategy to isolate a water-soluble polythiophene and to control its higher-order structure by a supramolecular approach is reported, that is, among a few bile acids, lithocholate can form stoichiometric complexes with cationic polythyphene to isolate the polymer chain, and the higher- order structure is changeable by the molar ratio.

TLDR
It is found that upon the addition of copper(II) trifluoromethanesulfonate to the chiral aggregates of poly-1 in a chloroform-acetonitrile mixture, the ICD disappears because of the oxidative doping of thepoly-1 main chain, while a further addition of amines such as triethylenetetramine induces undoping of thePoly-1 which results in the reappearance of the I CDs.
