Regioregular Pyridal[2,1,3]thiadiazole π-Conjugated Copolymers

Abstract: π-Conjugated, narrow band gap copolymers containing pyridal[2,1,3]thiadiazole (PT) were synthesized via starting materials that prevent random incorporation of the PT heterocycles relative to the backbone vector. Two regioregular structures could be obtained: in one the PTs are oriented in the same direction, and in the other the orientation of the PTs alternates every other repeat unit. Compared to their regiorandom counterparts, the regioregular polymers exhibit a 2 orders of magnitude increase of the hole mobilites, from 0.005 to 0.6 cm2 V–1 s–1, as determined by field-effect transistor measurements.

Product-related deception in e-commerce: a theoretical perspective

Abstract: With the advent of e-commerce, the potential of new Internet technologies to mislead or deceive consumers has increased considerably This paper extends prior classifications of deception and presents a typology of product-related deceptive information practices that illustrates the various ways in which online merchants can deceive consumers via e-commerce product websites The typology can be readily used as educational material to promote consumer awareness of deception in e-commerce and as input to establish benchmarks for good business practices for online companies In addition, the paper develops an integrative model and a set of theory-based propositions addressing why consumers are deceived by the various types of deceptive information practices and what factors contribute to consumer success (or failure) in detecting such deceptions The model not only enhances our conceptual understanding of the phenomenon of product-based deception and its outcomes in e-commerce but also serves as a foundation for further theoretical and empirical investigations Moreover, a better understanding of the factors contributing to or inhibiting deception detection can also help government agencies and consumer organizations design more effective solutions to fight online deception

Achieving Brand Loyalty Through Sponsorship: The Role of Fit and Self-Congruity

Abstract: Managers increasingly seek to develop brand loyalty through sponsorship activities, though this relationship has not been solidly established. This article models and demonstrates the impact of sponsorship on brand loyalty. The studied concepts and relationships emerge from both the sponsorship and consumer-brand relationship literature. The experimental design relies on before-and-after measurements and multiple exposures to the sponsorship. Thus this study demonstrates that sponsorship exposure has a positive impact on brand affect, brand trust, and brand loyalty. The change in brand loyalty from before to after sponsorship exposure reflects two persuasion processes. First, self-congruity with an event enhances brand loyalty through event and brand affect. Second, perceived fit between the event and the brand has a positive effect on brand affect, through attitude toward the sponsorship, and on brand trust, such that it ultimately influences brand loyalty. Brand affect is identified as an important mediator of sponsorship effects.

Red-Light-Emitting Iridium Complexes with Hole-Transporting 9-Arylcarbazole Moieties for Electrophosphorescence Efficiency/Color Purity Trade-off Optimization

Abstract: The synthesis, structures, photophysics, electrochemistry and electrophosphorescent properties of new red phosphorescent cyclometalated iridium(III) isoquinoline complexes, bearing 9-arylcarbazolyl chromophores, are reported. The functional properties of these red phosphors correlate well with the results of density functional theory calculations. The highest occupied molecular orbital levels of these complexes are raised by the integration of a carbazole unit to the iridium isoquinoline core so that the hole-transporting ability is improved in the resulting complexes relative to those with I-phenylisoquinoline ligands. All of the complexes are highly thermally stable and emit an intense red light at room temperature with relatively short lifetimes that are beneficial for highly efficient organic light-emitting diodes (OLEDs).
