Fluorescence of 2-Hydroxy Chalcone Analogs with Extended Conjugation: ESIPT vs. ICT Pathways.

The chalcone derivatives with hydroxy group () have been examined using low-temperature fluorescence spectroscopy. The study aimed to freeze the intramolecular charge transfer (ICT) motion in order to reveal the potential hidden transition(s) that are difficult to observe at room temperature. Although chalcone revealed one emission peak at ~667 nm at room temperature, it exhibited two emission peaks (λ = 580 and 636 nm) in EtOH at liquid N temperatures (77 K).

Pediatric to Adult Care Transition in the Hospital Context (PATCH) Tool: A Novel Tool to Assess Pediatric Institutional Guidelines for Inpatient Care of Adults.

Objective: The growing number of adults with childhood onset chronic conditions (COCC) is reflected in the increase of adult-aged admissions to pediatric institutions. Despite national bodies advising pediatric institutions to have a pediatric to adult health care transition (HCT) policy, little guidance is available on if or how to include inpatient care. We sought to create a framework-based Pediatric to Adult Transitional Care in the Hospital Context (PATCH) tool to assess how inpatient care of adults is addressed in pediatric institutional guidelines or policies (hereafter guidelines) as a first step towards informing future PATCH guideline development.

Attitudes towards models of abortion care in sexual and reproductive health: perspectives of Australian health professionals.

Background Abortion care is typically undertaken by doctors; however, alternate models, including nurse-led care, are increasingly seen as viable alternatives. However, attitudes towards the leadership of alternate models can be a barrier to change. We explored the acceptability of different models of abortion care, and whether attitudes differed by health profession for those working in sexual and reproductive health.

Bright NIR-Emitting Styryl Pyridinium Dyes with Large Stokes' Shift for Sensing Applications.

Two NIR-emitting donor-π-acceptor (D-π-A) type regioisomeric styryl pyridinium dyes (-) were synthesized and studied for their photophysical performance and environment sensitivity. The two regioisomers, and , exhibited interesting photophysical properties including, longer wavelength excitation (λ ≈ 530-560 nm), bright near-infrared emission (λ ≈ 690-720 nm), high-fluorescence quantum yields (ϕ ≈ 0.24-0.
