Highly Stabilized β‐Carotene in Carbon Nanotubes

Abstract

Encapsulation of β-carotene inside single-walled carbon nanotubes (SWCNTs) greatly improves the stability of β-carotene. The Figure shows a schematic illustration of β-carotene inside a SWCNT. The surrounding tube wall protects β-carotene from reacting with radical species and suppresses its isomerization. This protection counters the degradation of π-conjugated molecules, which is a bottleneck impeding their application in photonic devices.
