Usage

General Description

(4-phenylmethoxyphenyl) benzoate is a chemical compound formed by the esterification of benzoic acid with a molecule containing a phenyl ring and a methoxy group. It is commonly used as a sunscreen agent due to its ability to absorb ultraviolet (UV) radiation and protect the skin from sunburn and damage. (4-phenylmethoxyphenyl) benzoate is often included in sunscreens and other skincare products as a way to increase their SPF (Sun Protection Factor) rating and provide greater protection against the harmful effects of UV radiation. Additionally, (4-phenylmethoxyphenyl) benzoate is also used in the production of plastics, coatings, adhesives, and other industrial applications due to its UV-absorbing properties.

Enol Ester Intermediate Induced Metal-Free Oxidative Coupling of Carboxylic Acids and Arylboronic Acids

A facile, efficient and environmentally friendly methodology for the preparation of phenolic esters is realized via metal-free coupling of carboxylic acids and arylboronic acids. This sequential one pot reaction, employing methyl propiolate as an activating reagent, proceeds through the formation of enol ester intermediate, followed by a nucleophilic attack on the C-O bond under the oxidation of hydrogen peroxide. These studies display that enol esters, despite previously being overlooked as synthetic intermediates, would be the valuable building blocks for developing carbon–carbon and carbon–heteroatom bond-forming reactions.

Synthesis and properties of 2-phenylbenzoxazole-based luminophores for in situ photopolymerized liquid-crystal films

We report the synthesis of a series of blue-emitting 2-phenylbenzoxazoles (PBOs) substituted at either the 5- or 6-position of the benzoxazole ring and the para-position of the phenyl substituent. The thermal and optical properties of the materials can be rationalized in terms of the position of the substituent at the benzoxazole moiety and the electron-withdrawing or electron-donating character of the substituents. From the results, we conclude that the combination of an electron-donating substituent at the benzoxazole fragment and an electron-withdrawing one at the phenyl fragment has a more marked effect on the electronic properties of the aromatic PBO core than other possibilities. This particular combination gives luminophores that are suitable for optical applications on the basis of their high emission efficiency and photostability. In view of that, oriented films were prepared by in situ polymerization of a mixture of a liquid crystalline direactive matrix containing 5% (w/w) of the luminophore. The films exhibit linearly polarized emission.

Preparation of a novel cross-linked polymer for second-order nonlinear optics

A novel cross-linked pyroelectric polymer with pronounced second-order nonlinear optical properties has been prepared. A multistep synthesis with several selective transformations including a kinetic resolution (transesterification) with the highly enantioselective Candida antarctica lipase B, yielded the monomer 4''-{(R)-(-)-2[(10-acryloyloxy)decyl]oxy}-3-nitrophenyl 4-{4'-[(11-acryloyloxy)undecyloxy]phenyl}benzoate A2c which displayed a ferroelectric chiral smectic C phase with large spontaneous polarization (175 nC/cm2). The monomer was poled and subsequently cross-linked by in-situ photopolymerization in the surface-stabilized ferroelectric liquid crystalline state. The cross-linked pyroelectric polymer exhibited an electro-optical coefficient (r22-r12) of 15-35 pm/V.
