[Implementation of a Behavioral Medicine Oriented Concept in Cardiological Rehabilitation]. / Implementierung einer Verhaltensmedizinisch Orientierten Rehabilitation in der Kardiologie.

This study examined the implementation of a behavioral medicine oriented rehabilitation concept in a cardiological rehabilitation clinic. Psychotherapeutic interventions were based on an Acceptance and Commitment Therapy framework. Participants were treated in a behavioral cardiac rehabilitation program (BCR; n=149), or in a conventional cardiac rehabilitation program (CCR, n=100). We tested and compared the reach of the targeted group, the fidelity of the concept implementation in the BCR, as well as the completeness of the intervention (dose delivered) and the patient-reported behavioral medical treatment dose (dose received). Changes from beginning of rehabilitation until discharge with regard to mental and physical performance were assessed in both groups. BCR-patients were more impaired than CCR-patients, and they confirmed more behavioral medical content, a higher consistency of the behavioral medical strategy and a stronger gain of competence. Adherence ratings indicated a largely accurate implementation of the intervention. In both groups, depression, somatization, anxiety, heart anxiety, exercise self-efficacy expectation, and maximum power in bicycle ergometry improved statistically significant from admission to discharge. Large or nearly large effect sizes were found for avoidance behavior (d=0.78), somatization (d=0.82), depression (d=0.76), anxiety (d=0.72) and performance in bicycle ergometry (d=0.86) in the BCR. A further evaluation by means of a randomized controlled trial should follow this implementation study.

Triptycene-Bis(aroyleneimidazole)s as Non-Fullerene Acceptors: The Missing Links.

The syntheses of four triptycene-bis(aroyleneimidazole)s-the missing links with respect to the previously reported triptycene-mono(aroyleneimidazole)s and triptycene-tris(aroyleneimidazole)s-are presented. Their optoelectronic properties and use as non-fullerene acceptors in organic photovoltaics with poly({4,8-bis[(2-ethylhexyl)oxy]benzo[1,2-b:4,5-b']dithiophene-2,6-diyl}[3-fluoro-2-(2-ethylhexyl)carbonyl]thieno[3,4-b]thiophenediyl) (PTB7) as a donor are described; these systems reach a maximum power conversion efficiency of 2 %. Furthermore, the effect of molecular symmetry on the photovoltaic device performance is discussed.

π-Extended rigid triptycene-trisaroylenimidazoles as electron acceptors.

Two soluble isomeric acceptor molecules based on a triptycene core, which is connected to three aroylenimidazole units are described. Due to the inherent threefold axis, the molecules are soluble and thus could be fully photophysically characterized in solution and film. Additionally, the preliminary results of these acceptors in organic photovoltaic devices with two different donor materials are reported.

Highly selective molybdenum ONO pincer complex initiates the living ring-opening metathesis polymerization of strained alkynes with exceptionally low polydispersity indices.

The pseudo-octahedral molybdenum benzylidyne complex [TolC≡Mo(ONO)(OR)]·KOR (R = CCH3(CF3)2) 1, featuring a stabilizing ONO pincer ligand, initiates the controlled living polymerization of strained dibenzocyclooctynes at T > 60 °C to give high molecular weight polymers with exceptionally low polydispersities (PDI ∼ 1.02). Kinetic analyses reveal that the growing polymer chain attached to the propagating catalyst efficiently limits the rate of propagation with respect to the rate of initiation (kp/ki ∼ 10(-3)). The reversible coordination of KOCCH3(CF3)2 to the propagating catalyst prevents undesired chain-termination and -transfer processes. The ring-opening alkyne metathesis polymerization with 1 has all the characteristics of a living polymerization and enables, for the first time, the controlled synthesis of amphiphilic block copolymers via ROAMP.
