Self-Assembled Monolayers Made of Anthracene Moiety for Ultrathin Film Transistors |
초록 |
A new functionalized triethoxysilane bearing an X-shaped, anthracene-based semiconducting molecule on one arm was designed and synthesized as a precursor for the preparation of a self-assembled monolayer (SAM) on a SiO2 substrate. The 6-(5-((6-((5-hexylthiophen-2-yl)ethynyl)-9,10-bis(phenylethynyl)-anthracen-2-yl)ethynyl)thiophen-2-yl)hexyl 3-(triethoxysilyl)-propylcarbamate (BATHT-TEOS) was found to be stable and sufficiently reactive to form organic monolayers on hydroxylated SiO2 surfaces. The structures and properties of these SAMs were investigated using X-ray photoelectron spectroscopy, UV−vis absorption spectroscopy, photoluminescence (PL) spectroscopy, laser scanning confocal microscopy−PL spectrometry, and spectroscopic ellipsometry. In this work, BATHT-SAM was employed as an interfacial layer on SiO2 to fabricate ultrathin film transistors(UTFT). The device UTFT-II, fabricated on BATHT-SAM/SiO2, exhibited field effect mobility of 0.04 cm2V−1 s−1. |
