Tunable room-temperature phosphorescence and circularly polarized luminescence encoding helical supramolecular polymer

Supramolecular polymers with different functionalities have been continuously developed in the past decade because of their indispensable role in soft materials. However, pure organic supramolecular polymers with stable room temperature phosphorescence (RTP) emission were very rarely reported for the difficulties of synthesis and achieving RTP in solution. Herein, soluble helical supramolecular polymers with circularly polarized room-temperature phosphorescence were developed via a facile host-guest strategy. Through assembly, a transition from pure fluorescence to almost pure RTP emission was achieved. Adjusting the asymmetry of guest could easily control the chiroptical property of supramolecular polymers. This work provides new opportunities for the design and development of intelligent soft functional soft materials.
