Structure–property relationships of quinoxaline-based liquid crystals

Abstract

Quinoxaline derivatives with different molecular structures stabilizing liquid crystalline self-assembly are discussed in this review. This class of molecules can be systematically modified with careful molecular engineering to achieve different...

Sustainable and fast synthesis of functionalized quinoxalines promoted by natural deep eutectic solvents (NADESs)

“…The quinoxaline unit is embedded in a notable number of compounds showing manifold practical applications. In the field of materials chemistry, quinoxaline derivatives show liquid crystal properties, 1 are known as corrosion inhibitors, 2 and find wide use in photovoltaic devices. 3 On the other hand, these heterocyclic systems are also currently employed as anticancer agents, 4 for their recognized antiviral and antitubercular activities, 5 as well as for their many other important biomedical applications (Fig.…”

Calixarene Functionalized Supramolecular Liquid Crystals and Their Diverse Applications

“…Columnar (Col) phases are classified again based on the organization of these columns into different lattices, namely, hexagonal (Col h ), rectangular (Col r ), oblique (Col ob ), helical (H), and tetragonal (Col tet ), respectively (Figure ). , In recent years, more attention has been focused on discotic LCs, especially the Col phase due to its potential in organic electronics. − …”

A New Class of Solution Processable Pyrazino[2,3‐g]quinoxaline Carbazole Derivative Based on D–A–D Architecture for Achieving High EQE in Yellow and White OLEDs

“…[ 22 ] Quinoxaline derivatives also have been used in organic electronic devices like organic solar cells, [ 23,24 ] OLEDs, [ 25 ] and organic field effect transistors (OFETs). [ 26 ] They have also found application in the construction of supramolecular self‐assembling materials, [ 27 ] sensors, [ 28 ] and also as acceptor units in the building of D–A systems with low energy gaps. [ 29 ]…”

“…[22] Quinoxaline derivatives also have been used in organic electronic devices like organic solar cells, [23,24] OLEDs, [25] and organic field effect transistors (OFETs). [26] They have also found application in the construction of supramolecular self-assembling materials, [27] sensors, [28] and also as acceptor units in the building of D-A systems with low energy gaps. [29] Pei and co-workers developed tetrasubstituted pyrazino[2,3g]quinoxaline derivatives with thiophene and phenyl rings, which leads to varying extent of conjugation to achieve highefficiency active waveguide fibers.…”
