A scalable method to coat monochiral (7,5) semiconducting single‐walled carbon nanotubes with a monolayer coating of a range of technologically useful polymers such as poly(3‐hexylthiophene) (P3HT) and poly(9,9′‐dioctylfluorene‐ co ‐benzothiadiazole) (F8BT) is presented. Optical spectroscopy and atomic force microscopy measurements show that the semiconducting tube purity (>99%) obtained from the selective wrapping of nanotubes by polymers such as poly(9,9‐dioctylfluorenyl‐2,7‐diyl) (PFO) can be transferred to these other nanotube–polymer combinations by polymer exchange.
