Enhanced thermal and photo-stability of a para-substituted dicumyl ketone inter...

A ketodiacid, 4,4'-dicarboxylate-dicumyl ketone (3), has been intercalated into a Zn, Al layered double hydroxide (LDH) by a coprecipitation synthesis strategy. The structure and chemical composition of the resultant hybrid material (LDH-KDA3) were characterized by powder X-ray diffraction (PXRD), FT-IR, FT-Raman and solid-state 13C{1H} NMR spectroscopies, scanning electron microscopy (SEM), energy-dispersive X...

Unexpectedly flexible graphene nanoribbons with a polyacene ladder skeleton

A new conjugated ladder polymer with a polyacene skeleton was synthesized in a Aldol-type condensation protocol between benzylic and aryl-ketone side groups of suitably functionalized single-stranded precursor polymers. The photophysical behavior of the new conjugated polyacene ladder polymer PAL comprising a polyacene skeleton has been investigated by steady-state and time-resolved photoluminescence spectrosco...

Construct validity of two measures of self-forgiveness in Portugal: a study of ...

Several studies have suggested that self-forgiveness promotes psychological well-being. The state self-forgiveness scale (SSFS) and the differentiated self-forgiveness process scale (DSFPS) are two self-report questionnaires that assess self-forgiveness in psychotherapy, personal change, and health. The present study aims to examine the psychometric properties of the SSFS and the DSFPS in a Portuguese sample, h...

Room-Temperature Phosphorescence and Efficient Singlet Oxygen Production by Cyc...

The synthesis of five novel cyclometalated platinum(II) compounds containing five different alkynyl-chromophores was achieved by the reaction of the previously synthesized Pt-Cl cyclometalated compound (1) with the corresponding RC≡CH by a Sonogashira reaction. It was observed that the spectral and photophysical characteristics of the cyclometalated platinum(II) complexes (Pt-Ar) are essentially associated with...

Photoresponsive N,N′-disubstituted indigo derivatives

The synthesis and a comprehensive characterization of the excited state properties of five N,N′-substituted indigo (Ind) derivatives (acetyl-, benzoyl-, methoxybenzoyl-, nitrobenzoyl- and chlorobenzoyl-) was undertaken in various solvents and temperatures. In the excited state, rotation around the central double bond was found with N,N′-diacetylindigo (DAI) and N,N′-dibenzoilindigo (DBI) derivatives. Both DAI a...

Helping Clients Victimized by Intimate Partners Through Stages of Change: An Em...

Intimate partner violence results in extensive negative mental health outcomes including depression, posttraumatic stress, and anxiety. Moreover, victimized partners who experience cumulative episodes of abuse over time can also present severe afect dysregulation and interpersonal difculties. Preliminary evidence for existing psychological treatments shows that these are globally efective on a symptomatic level...

Positioning Microanalysis: A method for the study of the dialogical self-dynamics

From a dialogical and Bakhtinian theoretical stance, self-identity is seen a process and a product of the tensional relation between multiple perspectives or positions. Even in the midst of different dialogical approaches to self, there is an overarching consensus that the dialogical dynamics established by these different positions are a core element for understanding how identity works. One of the main proble...

“Let’s Dance”: A Dialogical Proposal for Analyzing Interactions and Positions i...

The dialogical self theory, based on the metaphor of the self as a dialogue between different voices and I-positions, conceptualizes the structure and functioning of the self as a product of communication and relational processes. The dynamics of the dialogical self imply the articulation between the individual self and the self in relationship with others. Yet, the dialogical self theory has been seldom applie...
