Usage

General Description

4-Hydroxyphenyl 4-(dodecyloxy)benzoate, also known as Eusolex 6300, is a chemical compound commonly used in sunscreens and other personal care products as a UV filter. It is a colorless crystalline solid that is soluble in organic solvents and has a melting point of about 68-70°C. 4-Hydroxyphenyl 4-(dodecyloxy)benzoate is known for its ability to absorb and block UV radiation, providing protection against sunburn and skin damage caused by exposure to the sun's harmful rays. It is considered to be an effective and safe ingredient in sunscreen formulations, offering broad-spectrum protection against both UVA and UVB radiation. Additionally, it is noted for its photostability, meaning it does not degrade or lose its efficacy when exposed to sunlight.

Photoconductive bent-core liquid crystalline radicals with a paramagnetic polar switchable phase

A series of self-organizing bent-core derivatives 1[12,n], containing a highly π-delocalized stable radical as the central angular structural element, is described. The planarity of the open-shell core permits efficient π-π stacking, which results in the formation of B2 and soft crystalline phases above 100 °C. Optical, XRD and dielectric analyses of 1[12,12] indicate that the ground state of the observed B2 phase is polar antiferroelectric of type SmCAPA exhibiting tristable electro-optical switching. SQUID and EPR measurements revealed strong antiferromagnetic spin-spin exchange interactions below the isotropic phase, which have been estimated at θ = -46 cm-1 with the Curie-Weiss law. Transient photoconductivity was observed in the B2 phase with a hole carrier mobility μh of 1.4 × 10-4 cm2 V-1 s-1

Symmetrical dimer liquid crystals with tilted smectic phases

Three, series of symmetrical dimer liquid crystals, i.e. bis(dodecyloxybenzoyloxybenzoyloxy)alkanes (BC12) and bis(dodecyloxy- and hexadecyloxybenzoyloxyphenyl) alkanedicarboxylates (QC12 and QC16) with a spacer ranging from two to eight methylene units,

The synthesis and mesomorphism of di-, tetra- and hexa-catenar liquid crystals based on 2,2′-bipyridine

2,2′-Bipyridines are known to coordinate to a wide variety of metal centres. In this paper, liquid-crystalline two-chained (dicatenar), four-chained (tetracatenar) and six-chained (hexacatenar) bipyridines are synthesised and their mesomorphism is described. For the tetracatenar bipyridines, a full homologous series, from tetramethoxy to tetratetradecyloxy, was synthesised, and the phase diagram showed a classic progression from nematic and smectic C phases at short chain length, through a cubic phase to a columnar phase.
