Temperature-Driven Planar Chirality Switching of a Pillar[5]arene-Based Molecular Universal Joint
Jiabin Yao,Wanhua Wu,Wenting Liang,Yujun Feng,Da-Yang Zhou,Jason J. Chruma,Gaku Fukuhara,Tadashi Mori,Yoshihisa Inoue,Cheng Yang +9 more
TL;DR: The study of an enantiopure bicyclic pillar-based molecular universal joint by single-crystal X-ray diffraction allowed for the first time the unequivocal assignment of the absolute configuration of a planar chiral pillar[5]arene by circular dichroism spectroscopy.
Journal ArticleDOI
Tuning the emissive triplet excited states of platinum(II) Schiff base complexes with pyrene, and application for luminescent oxygen sensing and triplet–triplet-annihilation based upconversions
TL;DR: The approach to tune the triplet excited states of Pt(II) Schiff base complexes will be useful for the design of phosphorescent transition metal complexes and their applications in light-harvesting, photovoltaics, luminescent O(2) sensing and upconversion, etc.
Journal ArticleDOI
Accessing the Long-Lived Triplet Excited States in Bodipy-Conjugated 2-(2-Hydroxyphenyl) Benzothiazole/Benzoxazoles and Applications as Organic Triplet Photosensitizers for Photooxidations
TL;DR: It is proposed that Bodipy derivatives containing excited state intramolecular proton transfer (ESIPT) chromophores 7-9 do not undergo ESIPT upon photoexcitation, as well as for applications of these compounds in photovoltaics, photocatalysis and luminescent materials, etc.
Journal ArticleDOI
Accessing the long-lived emissive 3IL triplet excited states of coumarin fluorophores by direct cyclometallation and its application for oxygen sensing and upconversion.
TL;DR: The results show that the ( 3)IL state can be readily accessed by direct cyclometallation of organic fluorophores and this approach will be useful for preparation and applications of transition metal complexes that show intense absorption in visible region and the long-lived emissive (3)IL excited states.
Journal ArticleDOI
Ruthenium(II) Polyimine–Coumarin Dyad with Non‐emissive 3IL Excited State as Sensitizer for Triplet–Triplet Annihilation Based Upconversion
TL;DR: It is proposed that it is unnecessary for a triplet sensitizers to be phosphorescent to sensitize a photophysical process such as TTA UC, and it is envisioned that non-phosphorescent transition metal complexes with triplet excited states populated upon photoexcitation can sensitize the TTAUC.
