New red-emitting Schiff base chelates: promising dyes for sensing and imaging of temperature and oxygen via phosphorescence decay time

Abstract

New complexes of Zn(ii), Pd(ii) and Pt(ii) with Schiff bases are prepared in a one step reaction and show photophysical properties particularly interesting for applications in optical sensors.

The dependence of oxygen sensitivity on the molecular structures of Ir(iii) complexes and their application for photostable and reversible luminescent oxygen sensing

“…And photostabilities of Ir(III) lms were measured in N 2 every 10 minutes. 51 The data in Fig. 10 indicated that emission intensities of Ir(III) lms were attenuated through continuous irradiation.…”

Photochemical anti–syn isomerization around the –N–N bond in heterocyclic imines

“…9 The are many photochemically-induced biological processes associated with nitrogen-containing heterocyclic compounds, such as Schiff's bases. 10,11 These compounds have shown a broad spectrum of applications in pharmacology and medicine, 12 but they also serve as catalysts, 13 optical materials and dyes, 14,15 and play an important role in inorganic biochemistry. 16,17 Depending on their structure, compounds of this type have a wide range of biological activities and are well-known for their antibiotic activities, including anticancer, antiviral and anticonvulsant effects.…”

Optical chemosensors for the gas phase detection of aldehydes: mechanism, material design, and application

“…The QDs based chemosensors usually have QDs loaded on glass, because the Si-O tetrahedral structure in glass contributes to provide a stable environment for the formation of QDs. 135 Moreover, cadmium telluride (CdTe) QDs are widely used because CdTe crystals are more stable, particularly under high temperature, maintaining high crystalline purity (i.e., with minimal defects), thus providing high yield of fluorescence.. 136,137,138 Several turn-off fluorescent probes based on QDs for FA detection will be discussed as follows.…”
