Advances in the Chemistry of 2,4,6‐Tri(thiophen‐2‐yl)‐1,3,5‐triazine

Abstract

Heterocyclic systems are now considered to be an integral part of material chemistry. Thiophene, selenophene, furan, pyrrole, carbazole, triazine and others are some such examples worth mentioning. 2,4,6‐Tri(thiophen‐2‐yl)‐1,3,5‐triazine is a C 3 h ‐symmetric system with thiophene as the donor unit and s ‐triazine as the acceptor unit. This review gives an insight into the advances made in the thienyl‐triazine chemistry over the past two to three decades. The synthetic pathways for arriving at this system and all its important derivatives are provided. The major focus is on the materials synthesized using the thienyl‐triazine system, including star molecules, linear and hyperbranched polymers, porous materials and their diverse applications. This review will play a catalytic role for new dimensions to be explored in thienyl‐triazine chemistry.

Tailoring Band Gaps in Thienyltriazine based Conjugated Porous Polymers through Comonomer Variation

“…The incorporation of thiophene and triazine units leads to various types of interactions in the resulting compounds. Introducing thienyltriazine allows for the creation of compounds with narrow band gaps, enabling the adjustment of structural and optical properties by modifying the degree of conjugation within the constituent groups [11] . Thienyltriazine has been used in porous polymers for a wide variety of energy applications, gas adsorption, purification purpose, and heterogeneous catalysis [12] .…”

[11] Thienyltriazine has been used in porous polymers for a wide variety of energy applications, gas adsorption, purification purpose, and heterogeneous catalysis. [12] Thienyltriazine has demonstrated effective band gap tuning in porous polymers, [13] as illustrated in previous research where we modified the linker/spacer while the thienyltriazine core was intact.…”

Tripodal Triazine and 1,8‐Naphthalimide‐based Small Molecules as Efficient Photocatalysts for Visible‐light Oxidative Condensation

“…[6,[26][27][28] Triazines are electron deficient in nature and thus are advantageous for electron conduction. [16,17] Triphenyl triazine ring has been substituted with donor chromophores such as phenothiazine, fluorene, [16] carbazole, [8,29,30] thiophene [2,8,31] and aromatic dendrimers consisting of triphenylamine [32,33] to obtain electron D-A molecules and have been widely studied. Such compounds have been utilized as photocatalysts for photoredox transformations after their incorporation in polymer networks, covalent organic frameworks (COFs) [12,18,19,34,35] and metal-organic frameworks (MOFs).…”
