Carmichael, Ian;Helman, W. P.;Hug, G. L. research published 《 Extinction coefficients of triplet-triplet absorption spectra of organic molecules in condensed phases: a least-squares analysis》, the research content is summarized as follows. A global least-squares technique was developed to assist in the critical evaluation of data consisting of large sets of measurements. The technique was designed to handle sets of data where many of the measurements are relative measurements. A linearization procedure was used to reduce the inherently nonlinear problem to a traditional multivariate linear regression. The technique was used to evaluate extinction coefficients, ε’s, of triplet-triplet absorption (TTA) spectra of organic mols. in condensed phases. A previous assumption, that there are no solvent effects on the TTA spectra, was investigated and modified so that a group of compounds measured in PhH was treated sep. The set of 445 ε’s obtained from the global least-squares fit, including these solvent effects, are presented. How these least-squares results can be used in a hierarchy of TTA ε standards is discussed. Further solvent effects such as the separation of polar and nonpolar media and the influence of temperature were probed.

A series of D-π-A type bipolar hosts based on triphenylene/carbazole were designed and synthesized. π-π Stacking of the triphenylene units between two adjacent mols. renders these hosts high electron mobilities above 1 × 10^-4 cm² V^-1 s^-1, and their electron and hole mobilities can be regulated through varying the connection position and π moieties.

D1-based green phosphorescent devices also exhibited the highest EQE of 18.6% with a reduced roll-off to 17.6% at 5000 cd m^-2 and 16.2% at 10 000 cd m^-2.
