General description

The multilayer desorption behavior of 2,5-diidothiophene was studied.[1]

Application

2,5-Diiodothiophene was used in the preparation of oligothiophene films.[2] It was used in maskless fabrication of periodic patterns of a conjugated polymer.[3] It was also used in fabrication of oligothiophene and polythiophene micropatterns.[4]

Maskless fabrication of periodic patterns of a conjugated polymer is achieved by regioselective condensation of 2,5-diiodothiophene on chemically patterned substrate surfaces followed by in situ photochemical conversion of the condensed molecules into oligothiophenes and polythiophenes. This approach utilizes preferential aggregation

This paper describes the details of surface reactions producing >100-nm-thick conjugated polymer films. When 2,5-diiodothiophene films deposited on copper are irradiated with UV at room temperature in Ar environments, oligothiophene films are synthesized. The average conjugation length of the produced

The multilayer desorption behavior of 2,5-diidothiophene and the dendritic aggregation of photochemical reaction products during the desorption of 2,5-diiodothiophene multilayers have been studied. Like many other aromatic compounds, 2,5-diiodothiophene shows a multilayer desorption behavior different from the typical zeroth-order kinetics
