Usage

General Description

Pentaerythrityl Tetrathiol is a chemical compound that consists of four thiol (sulfhydryl) groups attached to a pentaerythritol molecule. It is commonly used as a crosslinking agent in the production of various polymers, such as polyurethanes and epoxies, to improve their mechanical properties and chemical resistance. Pentaerythrityl tetrathiol is also utilized as a curing agent in the formulation of adhesives, coatings, and sealants. Additionally, it is used in the synthesis of specialty chemicals and pharmaceuticals. Due to its ability to form strong covalent bonds, pentaerythrityl tetrathiol is an important ingredient in the manufacturing of materials with high performance and durability.

Molecular rods based on oligo-spiro-thioketals

We report on an extension of the previously established concept of oligospiroketal (OSK) rods by replacing a part or all ketal moieties by thioketals leading to oligospirothioketal (OSTK) rods. In this way, some crucial problems arising from the reversible formation of ketals are circumvented. Furthermore, the stability of the rods toward hydrolysis is considerably improved. To successfully implement this concept, we first developed a number of new oligothiol building blocks and improved the synthetic accessibility of known oligothiols, respectively. Another advantage of thioacetals is that terephthalaldehyde (TAA) sleeves, which are too flexible in the case of acetals can be used in OSTK rods. The viability of the OSTK approach was demonstrated by the successful preparation of some OSTK rods with a length of some nanometers.
