Description

General description

1,2,3,4-Tetrahydronaphthalene (Tetralin), a bicyclic hydrocarbon, is a constituent of petroleum and coal tar. It is used in coal liquefaction and as an alternative to turpentine in paints and waxes. Degradation of tetralin by Corynebacterium sp. strain C125, and by pyrolysis have been reported. A study reports the transformation of naphthalene to tetralin in the presence of activated carbon supported molybdenum carbides. Dehydrogenation of tetralin by microwave heating in the presence of platinum-supported activated carbon has been investigated.

Application

1,2,3,4-Tetrahydronaphthalene may be used as a raw material in the synthesis of fullerenes.

Rotator side chains trigger cooperative transition for shape and function memory effect in organic semiconductors.

Hyunjoong Chung et al.

Nature communications, 9(1), 278-278 (2018-01-20)

Martensitic transition is a solid-state phase transition involving cooperative movement of atoms, mostly studied in metallurgy. The main characteristics are low transition barrier, ultrafast kinetics, and structural reversibility. They are rarely observed in molecular crystals, and hence the origin and
