Synthesis and investigation of the photophysical, electrochemical and theoretical properties of phenazine–amine based cyan blue-red fluorescent materials for organic electronics

Abstract

We report a study of the effect of modulating the donor system fused with a central phenazine core to understand the tuning of the optoelectrochemical properties in the designed phenazine–amine derivatives.

Synthetic strategies of phenazine derivatives: A review

“…The same year, Gajula and co-workers [83] reported an efficient approach of using condensation method in one pot to synthesize of various substituted phenazine derivatives (43)(44)(45)(46)(47)(48)(49)(50). As shown in Scheme 8, in general, 2-naphtol occurred self-coupling to form the intermediate of 1, 2-naphthoquinones had condensation in one pot to obtain target compound in good to excellent yields.…”

“…In sharp contrast, these synthetic strategies epitomize powerful alternatives with sustainable, facile, and highefficient principles for the formation of complex molecules, such as electrochemical strategy, biosynthesis, microwave method, supramolecular catalysis, photocatalysis, and some chemical synthesis [16,[44][45][46][47][48][49][50][51][52][53][54][55][56]. Notably, these strategies effectively avoid the major drawbacks of traditional methods and simultaneously provide concise process to furnish structurally various phenazine derivatives in good to excellent yields [49,[57][58][59][60][61][62][63].…”

Review of Conjugated Porphyrin Systems

“…This mechanism promotes the preparation of desirable sensors based on porphyrin/nanocarbon conjugates. 209 Porphyrin-CCG hybrids produce electrocatalytically active and electrochemically stable sensor systems to detect oxygen and hydrogen peroxide in solution. 210 With similar electrochemical procedures, porphyrins-GO hybrids can be used as sensors to detect serotonin.…”

Blue-red emitting materials based on a pyrido[2,3-b]pyrazine backbone: design and tuning of the photophysical, aggregation-induced emission, electrochemical and theoretical properties

“…From the literature, D–A molecules with acceptors such as quinoxaline, 6 indolo-quinoxaline, 7 pyrido[2,3- b ]pyrazine, 8 and phenazine 9 are well known, due to their excellent semiconducting and highly emissive properties with outstanding AIE and TADF characteristics. Here, the pyrido[2,3- b ]pyrazine acceptor is notable for its high electron-accepting ability, due to its additional pyridine N-atoms in the fused ring mimicking quinoxaline.…”
