BACKGROUND: Older adults are increasingly using information and communication technologies (ICTs). Recent studies show beneficial effects of using ICTs for older adults, particularly in terms of reducing loneliness and depression. However, little is known about the factors that may prevent discontinued ICT use in populations that may be at greater risk, such as those in continuing care retirement communities (CCRCs). OBJECTIVES: The purpose of this study is to examine a range of factors that may influence discontinued (1) ICT use, (2) searching for health information, and (3) searching for general information over time among CCRC residents...

Three reaction-based fluorescent probes based on two new naphthalimide platforms were developed for the detection of H2S. A new approach in detecting H2S by the reduction of an azide to a triazene intermediate in aqueous media is reported. Given their design features, these chemodosimeters provide useful insights into the relatively unexplored area of C0 spacers between receptor:reporter components. The N-aryl-1,8-naphthalimide platform features straightforward placement of the ICT and PET modulators on the same molecule...

The C40 carotenoid capsanthin is of photophysical interest because it belongs to the family of terminally carbonyl-substituted apocarotenes. These have the potential to exhibit intramolecular charge transfer (ICT) character in the excited state. We studied its ultrafast dynamics in different solvents using broadband transient absorption spectroscopy in the 260-1600 nm range. Photoexcitation initially populated the S2(1(1)Bu(+)) state which decayed to the S1(2(1)Ag(-)) state in 120-150 fs. The lifetime of the S1 state decreased from 10...

In the present investigation, an intramolecular charge transfer (ICT) and aggregation induced emission enhancement (AIEE) active donor-acceptor-donor (D-A-D) system 5 having fumaronitrile as the acceptor and hexaphenylbenzene (HPB) as the donor moieties joined through rotatable phenyl rings has been designed and synthesized that is highly emissive in the solid state and exhibits stimuli-responsive reversible piezochromic behavior upon grinding and heating. Because of its AIEE characteristics, HPB derivative 5 undergoes aggregation to form fluorescent aggregates in mixed aqueous media that exhibit ratiometric fluorescence response toward aliphatic amines (primary/secondary/tertiary) and turn-off response toward aromatic amines and hence differentiates between them...
