A simple method is reported for the preparation of double‐helical structures through a series of achiral random and block copolymers poly(styrene‐co‐4‐vinylbenzyl triazolylmethyl methylthymine) (PS‐co‐PVBT) with various T units on the side chains through click reactions of poly(styrene‐co‐4‐vinylbenzyl azide) (PS‐co‐PVBN3) with propargyl thymine (PT) and also the synthesis of the A‐appended pyrene derivative (A‐Py) through click chemistry. This double‐helical structure is observed from achiral random‐coil polystyrene (PS) main chains, stabilized through the combination of multiple A–T hydrogen bonds, and π–π stacking between pyrene units and single‐walled carbon nanotubes (SWCNTs).
