A series of compounds based on the angular-shaped naphthalene tetracarboxylic diimide core have been synthesized, characterized and used as active layers of organic field-effect transistors (OFETs). The fabricated OFET devices exhibit n-type semiconducting characteristics, demonstrating the first examples of semiconductors based on angular-shaped naphthalene tetracarboxylic diimides.

The exponential rise in the density of silicon CMOS transistors has now reached a limit and threatening to end the microelectronics revolution. To tackle this difficulty, group III–V compound semiconductors due to their outstanding electron transport properties and high mobility are very actively being researched as channel materials for future highly scaled CMOS devices. In this paper, we have...

This paper describes physical-organic studies of charge transport by tunneling through self-assembled monolayers (SAMs), based on systematic variations of the structure of the molecules constituting the SAM. Replacing a -CH(2)CH(2)- group with a -CONH- group changes the dipole moment and polarizability of a portion of the molecule and has, in principle, the potential to change the rate of charg...

Recent investigations have shown the oxone-mediated oxidative methyl esterification of benzaldehyde derivatives using methanol. The reactions were accelerated in the presence of indium(III) triflate, a trivalent indium reagent, in many cases. Based on this method of methyl esterification of benzaldehyde derivatives, we further explored an application to heterocyclic aldehydes. The reactions wer...

The different arrangements and combinations in which carbon can exist produce a wide variety of compounds that have unique physical, chemical and electrical properties. Some of these allotropes behave as conductors while others are classified as semiconducting. Our efforts focused on taking advantage of the carbon-based materials’ potential and optimally we employed them together to form an all...

there is no organometalic compound of indium known to exist naturally in the human body. however, a number of compounds prepared with ¹¹¹in have been evaluated for localization studies. the useful radioactive decay characteristics and the suitable chemical properties of the metal ion have drawn attention of many investigators resulting in the preparation of numerous ¹¹¹in labeled compounds for ...

This study describes, for the first time, in situ generation of indium organometallic reagents environmentally friendly deep eutectic solvents (DESs). The allylation process different carbonyl compounds is achieved mediated by metal and using cheap allyl chloride derivatives. unique DES properties allow to perform reaction at room temperature under air, obtaining yields ranging from 45% 99%. It...

OBJECTIVES Inhalation toxicities of indium-tin oxide (ITO) and indium oxide (IO) in mice were characterized in comparison with those previously reported in rats. METHODS B6C3F(1) mice of both sexes were exposed by inhalation to ITO or IO aerosol for 6 h/day, 5 day/wk for 2 wk at 0, 0.1, 1, 10 or 100 mg/m(3) or 13 wk at 0, 0.1or 1 mg/m(3). RESULTS ITO and IO particles were deposited in the l...
