“The

authors examined the experimental effects of social context on everyday problem-solving performance by older, middle-aged, and younger adults. Participants were presented with six everyday problems constructed by framing two behavioral challenges in social contexts representative of the lives of older, middle-aged, and younger adults. As predicted, participants performed best when problems were situated in contexts representative of their own age group. Older adults also outperformed the other age groups on problems set in older adult contexts, check details suggesting that when problems are set in ecologically relevant contexts, one may not observe previously reported age-related declines in performance.”
“A series of bipolar OLED materials were subjected to pulsed radiolysis experiments to determine their transient absorption and lifetime profiles of the independently in situ generated radical cations and anions in solutions. Moreover, their emission behaviors from the charge recombination of their

radical ions were also determined by the pulse radiolysis method. It was found the absorption bands in SIS3 purchase doubly ortho-linked quinoxaline/diphenylfluorene hybrids la-e are red-shifted progressively with increasing electron-donating nature at the C5 and C8 positions of the quinoxaline template. The incipient radical anions in la-e are mainly localized on the quinoxaline heterocyclic moiety, whereas the incipient radical cations are mainly distributed selleck onto the attached electron-donating groups at the C5 and C8 positions of the quinoxaline template. For other doubly ortho-linked cis-stilbene derivatives 3d, 3f, and 0, the radical anions are mainly localized on

the cis-stilbene central moiety and the radical cation is mainly distributed onto both para substituents of the cis-stilbene templates. It was also shown that there is a correlation between their optoelectronic emission efficiencies and the radiolysis induced emission intensities. In addition, the charge transporting behaviors within an OLED device were found to show the relationship with transient absorption half-lives (tau(1/2)) of the radical ions. Charge recombination mechanisms in both the OLED and pulsed radiolysis experiments were proposed to rationalize these observations, allowing us to establish some guidelines for an ultimate molecular design of ideal bipolar optoelectronic materials with a judicious choice of local charge appendages in the optoelectronic templates.”
