Summary: This study reports an excitation-wavelength-responsive and time-dependent multicolor p-RTP emission pseudopolyrotaxanes supramolecular system. The reversible adjustment of p-RTP can be achieved through the photoisomerization of diarylethylene, offering potential applications in information storage and treatment.

Summary: The study demonstrates successful realization of reversible switching between fluorescence and phosphorescence through light control, using the effective strategy of integrating o-BFT with dibenzofuran and dithienylbenzothiophene. The dual emission of fluorescence and RTP in o-BFT can be controlled through alternate UV and visible light irradiations. The study suggests the domination of photo-controlled triplet-to-singlet Forster resonance energy transfer in triplet inactivation, preserving the initial fluorescence for photoreversible fluorescence-RTP switching.

Summary: Two kinds of amorphous solid-state supramolecular systems with purely organic room temperature phosphorescence (RTP) were reported, which were activated by calix[3]phenothiazine (C[3]Pz) and 1,2-/1,3-dicyanobenzene (1,2-/1,3-DCB). The RTP of these supramolecular systems was entirely from the interaction between 1,2-/1,3-DCB and C[3]Pz, forming dense supramolecular complexes, leading to two different phosphorescence emissions. The use of 1,2-DCB and 1,3-DCB as molecular rivets fixed the C[3]Pz, inhibiting molecular vibration and reducing nonradiative relaxation, resulting in effective RTP emission with high quantum yields.

Summary: It is discovered that chitosan not only has its own room-temperature phosphorescence (RTP), but also reacts with different phosphorescent molecules to obtain a colorful and long-afterglow RTP material. The obtained polymer films have ultra-long RTP and lifetimes of up to seconds by grafting different phosphorescent molecules onto chitosan and using host-guest interactions.

Summary: This research presents a method to transform the organic single-component small molecule N-BOX between high-efficiency blue and yellow RTP with multilevel stimuli-responsiveness under external stimuli. The RTP emission of N-BOX in the crystalline state is easily adjustable by external stimuli, leading to unique multilevel stimuli-responsiveness.

Summary: In the past decade, supramolecular polymers with different functionalities have been continuously developed for their crucial role in soft materials. However, pure organic supramolecular polymers with stable room temperature phosphorescence (RTP) emission are rarely reported due to synthesis difficulties. In this work, soluble helical supramolecular polymers with circularly polarized room-temperature phosphorescence were successfully developed, providing new opportunities for the design and development of intelligent soft functional materials.

Summary: This study proposes a strategy of coordination-induced structural rigidity to achieve enhanced room temperature phosphorescence (RTP) of aluminum/scandium-doped phosphorescent microcubes (Al/Sc-PMCs) in aqueous solution. The coordination-induced rigidity strategy involves the combination of metal sites on the surface of Al/Sc-PMCs with water molecules through strong coordination, followed by the binding of these coordinated water molecules with surface groups through hydrogen bonding interaction. This rigidifies the chemical groups and inhibits their motions, resulting in enhanced RTP efficiency.
