Solvent-Induced Sign Inversion of Circularly Polarized Luminescence: Control of Excimer Chirality by Hydrogen Bonding

open access: yesJournal of the American Chemical Society, 2020
A series of pyrenes sandwiched by axially chiral 1,1'-binaphthyls were synthesized. Among them, (R,R)-3 possessing 2-hydroxy-3,3'-dimethylbinaphthyls exhibited solvent-dependent inversion of the sign of circularly polarized luminescence (CPL) without a ...

Hot Vibrational States in a High-Performance Multiple Resonance Emitter and the Effect of Excimer Quenching on Organic Light-Emitting Diodes

open access: yesACS Applied Materials & Interfaces, 2021
The photophysics of multiple resonance thermally activated delayed fluorescence molecule ν-DABNA is described. We show coupling of a 285 cm–1 stretching/scissoring vibrational mode of peripheral phenyl rings to the S1 state, which dictates the ultimate ...

Annihilation Versus Excimer Formation by the Triplet Pair in Triplet–Triplet Annihilation Photon Upconversion

open access: yesJournal of the American Chemical Society, 2019
The triplet pair is the key functional unit in triplet–triplet annihilation photon upconversion. The same molecular properties that stabilize the triplet pair also allow dimers to form on the singlet energy surface, creating an unwanted energy relaxation

Influence of the anterior chamber depth on the accuracy of the intraocular lens optical power calculation in short eyes [PDF]

open access: yesКлиническая практика, 2020
Background. The calculation of the optical strength of the intraocular lens (IOL) in eyes with a short anterior-posterior axis presents significant difficulties due to non-standard anatomical parameters of the eye, including the anterior chamber depth ...
