Usage

Description

2-NITROPHENYL OCTYL ETHER (NPOE) is an organic compound that consists of a nitrophenyl group attached to an octyl ether group. It is known for its unique chemical properties and potential applications in various industries.

Uses

Used in Polymeric Inclusion Membranes (PIMs):
2-NITROPHENYL OCTYL ETHER is used as a plasticizer in a polymeric inclusion membrane (PIM) for enhancing the transport of copper(II) in the solution of ammonia. Its incorporation into the PIM improves the membrane's selectivity and permeability, making it an effective tool for copper(II) transport.
Used in Cellulose Tri-Acetate/Carbon Nanotube (CTA/CNT) Based Membranes:
2-NITROPHENYL OCTYL ETHER is used as a component in cellulose tri-acetate/carbon nanotube (CTA/CNT) based membranes, which are employed in the transport and detection of melamine from milk samples. The presence of NPOE in the membrane contributes to its selectivity and sensitivity, allowing for efficient melamine detection and removal from milk products.

Quinolines by three-component reaction: Synthesis and photophysical studies

The synthesis of five quinolines 8-octyloxy-4-[4-(octyloxy)phenyl]quinoline and 6-alkoxy- 2-(4-alkoxyphenyl)-4-[(4-octyloxy)aryl]quinolines are described by three-component coupling reaction mediated by Lewis acid FeCl3 and Yb(OTf)3. 4-n-octyloxybenzaldehyde, anisaldehyde, 4-n-octyloxyaniline p-anisidine, and 1-ethynyl-4-heptyloxybenzene, 1-ethynyl-4-octyloxybenzene and 2-ethynyl-6-heptyloxynaphthalene are the reagents in this protocol. A Yb3+ catalyst resulted in higher yields of quinolines than Fe3+. Polarizing optical microscopy (POM) revealed that none of the quinolines were liquid crystals, even the more anisotropic. UV-Vis measurements of one of the quinolines in polar solvent show two absorption bands at 280 and 350 nm related to π,π?and n,π?transitions. No changes were observed to lower-energy absorption band (ε 4 mol L-1 cm-1) related to n,π?transition. A laser flash photolysis study for one of the quinolines relates a main transient band at 450 nm with a lifetime of 2.6 μs in ethanol, which is completely quenched in the presence of oxygen. This transient band was assigned to triplet-triplet absorption of one of the quinolines, which is semi-oxidised in the presence of phenol. Radiative rate constants have been determined along singlet and triplet excited state energies (3.39 and 3.10 eV, respectively). The chemical structure of one of the quinolines was also unequivocally confirmed by single-crystal X-ray analysis.
