Triazine is an aromatic six-membered-heterocyclic ring with three nitrogen atoms increasing its electron-accepting ability. Linking triazine building blocks with other electron-releasing units can provide a photoactive electron transfer platform. CTFs, as 2D triazine-based COFs, structures extending organic functional groups outward the triazine ring in a periodically arranged scaffold. The similarities of CTFs with g- C3N4 gained the attention of researchers in the photocatalysis field. Moreover, the CTFs band structures can be easily controlled by changing the electron-releasing building blocks linked to the triazine moieties [24, 25]. Based on the theoretical calculations, the number of stacking layers, nitrogen contents, and pore size can affect the electronic properties of CTFs. The latter is due to the quantum confinement effect.

Triazine is a class of nitrogen containing heterocycles. The parent molecules’ molecular formula is C3H3N3. They exist in three isomeric forms: 1,3,5-triazines, being common. The triazines have planar six-membered benzene-like ring but with three carbons replaced by nitrogen’s.

Triazines are herbicides that have been heavily applied to control weeds in agricultural, industrial, and urban areas. These herbicides are persistent in the environment and due to their water solubility, they may contaminate groundwater.

wTo extenuate the sweet corrosion, organic corrosion inhibitors are used, which adsorb on the steel surface and provide protection from the aggressive attack of the corrosive electrolyte. Most of the effective inhibitors come from the class of the nitrogen-containing compounds e.g. imidazolines, amides, etc. [11–17]. However, these molecules require cumbersome and tedious synthetic procedures and are mostly toxic [5,18,19]. The 1,3,5-triazines are six-membered aromatic heterocyclic rings. Hexahydrotriazines are the reduced derivatives of the 1,3,5-triazines. The choice of 1,3,5-triazines as corrosion inhibitors stems from the fact that they exhibit non-toxic characteristics, given their wide application as antibacterial, anticonvulsant, antimicrobial, antitumor, anti-inflammatory, and analgesic agents [20–25]. They also possess electronegative functional groups and π-bonds that furnish lone pair of electrons that enable a corrosion inhibitor molecule to adsorb effectively on a metal surface [26,27]. There are a number of reports available on the application of the triazine-based corrosion inhibitors [28–33]. However, there is no study available on the application of triazines as inhibitors for the sweet corrosion environment.

Triazines are a fundamentally important class of aromatic molecules. They are present in many bioactive compounds and they play a key role in a number of biological processes [1]. 1,2,4-Triazine is one of the possible three isomers of the six-membered ring bearing three nitrogen atoms. In the past, this system was also called as-triazines (asymmetric triazines). 1,2,4-Triazine ring is widely described as scaffold of many biological active compounds, natural or synthetic, with a great variety of pharmacological effects, especially active as antitumor agents, anti-AIDS agents [2], CRF receptor antagonists [3], antimicrobial, and antiinflammatory agents [4]. The NCNN sequence of the 1,2,4-triazine ring was considered fundamental for various pharmacological activities.
Aqueous Biphasic Systems Composed of Random Ethylene/Propylene Oxide Copolymers, Choline Acetate, and Water for Triazine-Based Herbicide Partitioning Study

Triazine-based herbicides are widely applied in agricultural production due to their low cost and high selectivity on many important weeds.[1,2] However, their prolonged use causes a risk to nontarget environments and organisms.[1,3] For example, atrazine is reported to be an endocrine disruptor for animals and human beings at low concentrations (~1.0–2.5 mg/kg day).[3–5] Their effect at such low concentrations emphasizes the need for sensitive methodologies for their determination. However, these analyses in real samples present challenges due to their complex matrices, and thus, the sample preparation step becomes indispensable to isolate the analytes.
