Luminescent materials incorporating pyrazine or quinoxaline moieties

Luminescent materials incorporating pyrazine or quinoxaline moieties

Though the past few decades, the development of new luminescent materials has received a lot of attention due to their applications as fluorescent sensors, in biological microscopy and in optoelectronic devices. Most of these applications are relied on intramolecular charge transfer (ICT). Presence of electron withdrawing N-heterocycles such as pyrazine and quinoxaline rings appeared therefore ...

SYNTHESES AND REACTIONS OF PYRAZINE AND QUINOXALINE 1.1 Pyrazine

Synthesis and characterization of novel iminobenzoates with terminal pyrazine moieties

Apart from its numerous biological activities like antidiabetic, anti-inflammatory, antimicrobial, pyrazine moiety plays an important role in luminescent materials. Its role in luminescent materials is due to its highly electron deficient nature specially when it is in the centre along the mainstay of extended π-conjugated systems. Similarly, new liquid crystalline compounds are being made cons...

Switchable Materials Containing Polyzwitterion Moieties

In recent decades, the design and construction of smart materials capable of switching into a polyzwitterionic state by an external trigger have been intensively pursued. Polyzwitterionic states have unique antifouling and surface properties and external triggers, such as pH, light, ions, electric field and CO2, cause significant changes in materials with regard to overall charge, ionic strengt...
