Organic Persistent RTP Crystals: From Brittle to Flexible by Tunable Self-Partitioned Molecular Packing

Arui Huang et al.

Summary: Organic RTP crystals with elastic/plastic deformation are achieved by controlling molecular configurations. These crystals have divisional aggregation structures of aromatics and alkoxy chains, and the RTP property can be modulated. The highest record of RTP lifetime is 972.3 ms for organic flexible crystals. The relationship among elastic/plastic deformation, RTP property, and aggregated structures is established, and a new approach for the development of flexible RTP crystals is explored.

Organic Binary and Ternary Cocrystal Engineering Based on Halogen Bonding Aimed at Room-Temperature Phosphorescence

Ayano Abe et al.

Summary: There is currently significant interest in pure organic room-temperature phosphorescence (ORTP) in cocrystals composed of 1,4-diiodotetrafluorobenzene (DITFB) and various polycyclic aromatic hydrocarbons (PAHs) or their derivatives. The relationship between crystal packing motifs and ORTP characteristics in binary cocrystals of DITFB and PAHs (phenanthrene, chrysene, and pyrene) is investigated. The interactions between sigma-hole center dot center dot center dot pi and pi-hole center dot center dot center dot pi not only determine crystal packing motifs but also affect photoluminescence quantum yields (PLQYs).

The host-guest inclusion driven by host-stabilized charge transfer for construction of sequentially red-shifted mechanochromic system

Dongdong Sun et al.

Summary: Developing a better understanding of the structure-property relationship of mechanochromic luminescent molecules is challenging. In this research, the authors demonstrate the impact of host-guest interactions on the mechanochromic properties of organic molecules. They observe bathochromic-shifted emission in a series of pyridinium-functionalized triphenylamine derivatives upon mechanical stimulation, which form homoternary host-guest inclusion complexes through charge transfer interactions. The study also involves a heteroternary complex that exhibits mechanochromic luminescent property. This work not only uncovers the effect of host-guest inclusion on mechanochromic properties, but also offers a principle and a simple approach to design sequentially red-shifted mechanochromic materials.
