Intrinsically stretchable fully π-conjugated polymers with inter-aggregate capillary interaction for deep-blue flexible inkjet-printed light-emitting diodes by Mingjian Ni, Zhiqiang Zhuo, Bin Liu, Xu Han, Jing Yang, Lili Sun, Yuekuan Yang, Jiangli Cai, Xiang An, Lubing Bai, Man Xu, Jinyi Lin, Quanyou Feng, Guohua Xie, Yutong Wu, Wei Huang

“…The loose rod-shaped stacking of asymmetric conjugated polymers chain in the precursor printed ink makes it easier to improve the intrinsic stretchability of inkjet-printed films. More interestingly, the anisotropic shape rod-like aggregate of conjugated polymers chains also induced a strong capillary interaction and further suppressed the coffee-ring effect, which is more likely to allow for uniform deposition during printed processing and form uniform printed films.…”

Conjugated Ladder Polymers: Unique Organic π-Conjugated Materials for Optoelectronics, Transistors, and Energy Harvesting and Storage by Kok Chan Chong, Teck Lip Dexter Tam, Ran Tao, Kang Le Osmund Chin, Ming Hui Chua, Jianwei Xu

“…Conjugated ladder polymers (cLPs) are polymers consisting of continuous fused aromatic rings with π conjugation along their backbone. This unique structure imparts cLPs with exceptional thermal, mechanical, and electrochemical stability, as well as notable optical and electrical properties due to their rigid, planar structures. …”

[(2-Dimesitylboryl)phenyl]ethynyl-Substituted [2.2]Paracyclophane Exhibiting Circularly Polarized Luminescence in Both Solution and Solid-State by Lianfeng Guo, Mengyuan Zhang, Cuihua Zhao

“…In addition, this compound can emit strong blue fluorescence in the solid state with quantum yields that are even much higher than in solution (<i>Φ</i>_F up to 0.64 in powder and spin-coated film). Moreover, the enantiomeric forms of <b><i>m</i>-BPhANPh₂-Cp</b> can show strong CPL signals in both dilute solution and solid state with |<i>g</i>_lum|s up to 9.6 × 10⁻³ and 5.4 × 10⁻³, respectively. …”
