Organic optoelectronic functional materials featuring circularly polarized emission and persistent luminescence represent a novel research frontier show promising applications in data encryption, displays, biological imaging, so on. Herein, we present simple universal approach to achieve organic phosphorescence (CPP) from amorphous copolymers by the incorporation of axial chiral chromophores into polymer chains via radical cross-linked polymerization. Our experimental reveal that (R/S)-PBNA...
Abstract Organic phosphorescent materials have attracted wide attention in recent years owing to their opportunities various functional applications. Through appropriate molecular design strategies and synthetic perspectives modulate weak spin–orbit coupling, highly active triplet excitons, ultrafast deactivation, the organic phosphors can be endowed with long‐lived room temperature phosphorescence (RTP) characteristics. cocrystals constructed by noncovalent intermolecular interactions...
Abstract Intermolecular interactions, including attractive and repulsive play a vital role in manipulating functionalization of the materials from micro to macro dimensions. Despite great success generation ultralong organic phosphorescence (UOP) by suppressing non-radiative transitions through interactions recently, there is still no consideration on UOP. Herein, we proposed feasible approach introducing carboxyl groups into phosphors, enabling formation intense between isolated molecules...
Abstract Organic phosphors offer a promising alternative in optoelectronics, but their temperature‐sensitive feature has restricted applications high‐temperature scenarios, and the attainment of phosphorescence (HTP) is still challenging. Herein, series organic cocrystal are constructed by supramolecular assembly with an ultralong emission lifetime up to 2.16 s. Intriguingly, remarkable stabilization triplet excitons can also be realized at elevated temperature, green exhibited solid state...
Dynamic room-temperature phosphorescence (RTP) in organic materials is highly sensitive toward changes of external stimulus, representing the expansion static RTP with fixed properties, and has gradually captured considerable attention. Different from big breakthroughs materials, dynamic remain a clear improvement over luminescent mechanisms molecular design rule. Therefore, we have reviewed progress to provide insight into behaviors lifetime, color, intensity, efficiency under different...
Abstract Ultralong organic phosphorescence (UOP) crystals have attracted increased attention due to the distinct photophysical property of a long-lived lifetime. However, are generally brittle, leading serious problem for their application in flexible technology. Herein, we report three types elastic (EOCs) with ultralong via introducing halogen atoms (Cl, Br, I) into π-conjugated phosphorescent molecules. Especially, crystal containing iodine displayed both excellent elasticity ( ε = 3.01%)...
Developing ultralong organic phosphorescence (UOP) materials with smart response to external stimuli is of great interest in photonics applications, whereas the manipulation molecular stacking on tuning such dynamic UOP still a formidable challenge. Herein, we have reported two polymorphs distinct photoactivated behavior based pyridine derivative for first time. Our experiment revealed that including photoactivation and deactivation feature highly dependent irradiation intensity...
Abstract The design of molecular compounds that exhibit flexibility is an emerging area research. Although a fair amount success has been achieved in the plastic or elastic crystals, realizing multidimensional and bending remains challenging.
