New emitters that can harvest both singlet and triplet excited states to give 100% internal conversion of charge into light, are required to replace Ir based phosphors in organic light emitting diodes (OLEDs). Molecules that have a charge transfer (CT) excited state can potentially achieve this through the mechanism of thermally activated delayed fluorescence (TADF). Here, it is shown that a D–A charge transfer molecule in the solid state, can emit not only via an intramolecular charge transfer (ICT) excited state, but also from exciplex states, formed between the molecule and the host material. OLEDs based on a previously studied D–A–D molecule in a host TAPC achieves >14% external electroluminescence yield and shows nearly 100% efficient triplet harvesting. In these devices, it is unambiguously established that the triplet states are harvested via TADF, but more interestingly, these results are found to be independent of whether the emitter is the ICT state or the D–A–D/host exciplex. 相似文献

Erythritol tetranitrate (ETN) is a melt‐castable explosive with impressive performance, similar to the well‐known related nitrate ester, pentaerythritol tetranitrate (PETN). Though ETN has been known since 1849, its properties have not been thoroughly investigated. We report here the first 1/2′′ copper cylinder tests of ETN, compared with PETN. We discuss detonation and wall expansion velocity, along with diameter effect information in unconfined rate stick tests. The detonation velocity of ETN is 99 % that of PETN in the same test setup, showing that performance properties are very similar for the two nitrate esters. 相似文献

The major youth psychotherapy meta-analyses have relied on published studies, which may have led to biased effect size estimates. To examine this possibility, the authors compared 121 dissertations with 134 published studies and found the following: (a) few differences on individual methodological variables, but, overall, stronger methodology in dissertations; (b) no differences in the steps taken to ensure treatment integrity; and (c) a mean dissertation effect size less than half that of published studies. The effect size difference remained robust across tests controlling for all reliable method differences. The findings suggest that dissertations are so strong, both methodologically and clinically, that they warrant inclusion in child psychotherapy meta-analyses and that previous meta-analyses, by excluding them, may have overestimated treatment effects.

The authors describe psychometric characteristics of the new Therapy Process Observational Coding System-Alliance scale (TPOCS-A; B. D. McLeod, 2001) and illustrate its use in the study of treatment as usual. The TPOCS-A uses session observation to assess child-therapist and parent-therapist alliance. Both child and parent forms showed acceptable interrater reliability and internal consistency; when applied to cases treated for internalizing disorders, both forms were associated with youth outcomes. Child-therapist alliance during treatment predicted reduced anxiety symptoms at the end of treatment. Parent-therapist alliance during treatment predicted reduced internalizing, anxiety, and depression symptoms at the end of treatment. The findings held up well after confounding variables were controlled, which suggests that both child-therapist and parent-therapist alliance play key (and potentially different) roles in the outcome of treatment as usual.

Although tetrathiafulvalene (TTF) and its derivatives have been extensively studied for more than 25 years as π-electron donors in intermolecular charge-transfer materials, the intriguing potential of TTF as a donor in an intramolecular sense has only recently been developed. Many versatile, functionalized TTF building blocks are now readily available, and this article will review a range of compounds in which TTF is covalently linked to an electron acceptor moiety by a variety of linking units, sometimes giving rise to an intramolecular charge-transfer (ICT) interaction, which is most frequently manifested in the optical and electrochemical properties. In this context, acceptor subunits include: tetracyano-p-quinodimethane, quinones, electron-deficient aryl groups, pyridinium and bipyridinium units, fullerenes, phthalocyanines, and mesomerically conjugated carbonyl, thiocarbonyl, ester, and related groups. This work paves the way for more systematic and detailed studies of TTF–spacer–A molecules (where A is an acceptor) in which there is increased control of the structural, electronic, optical, and magnetic properties arising from ICT interactions in the ground state, or in the excited state. 相似文献
