Abstract

7-Didodecyn-1-yl[1]benzothieno[3

2-b]

[1]benzothiophene (C10-BTBT) was synthesized in the base of o-chlorobenzaldehyde

NaSH

O and decanoyl chloride by elimination reaction

acrylation reaction and reduction reaction.The structure of compound was confirmed by

HNMR. The properties of optical

electrical and environmental stability were studied. Its optical properties were characterized by the UV absorption and fluorescence spectra.The results indicated that maximum emission peak of the compound is at 352 nm which is the typical blue fluorescene.The phase transition temperature was measured by DSC

=112 ℃

=125 ℃.The OTFT devices with bottom-gate and top-contact structure based on C10-BTBT were preparated by inkjet printing method

the average field-effect mobility was up to 0.1 cm

/Vs and the maximum mobility was 0.25 cm

/Vs

the on/off curruent ratio exceeded 10

. Organic thin-film transistor was placed in air different time

The on/off current

on/off ratio of organic thin-film transistor had no more changes.
