Thiophene-Furan oligomers: Beyond-DFT Study of Electronic and Optical Properties

Journal: :Electronic structure 2022

Abstract Thiophene oligomers are an important class of organic materials for photovoltaic applications, owing to their unique optoelectronic properties. Recently it has been suggested that incorporation furan units the thiophene chains, maintaining chain structure, namely thienylfuran linear oligomers, can bring improvements final material. In this work, we present a theoretical study thiophene...

Electrical transport properties of oligothiophene-based molecular films studied by current sensing atomic force microscopy.

Journal: :Nano letters 2011

Bas L M Hendriksen Florent Martin Yabing Qi Clayton Mauldin Nenad Vukmirovic Junfeng Ren Herbert Wormeester Allard J Katan Virginia Altoe Shaul Aloni Jean M J Fréchet Lin-Wang Wang Miquel Salmeron

Using conducting probe atomic force microscopy (CAFM) we have investigated the electrical conduction properties of monolayer films of a pentathiophene derivative on a SiO(2)/Si-p+ substrate. By a combination of current-voltage spectroscopy and current imaging we show that lateral charge transport takes place in the plane of the monolayer via hole injection into the highest occupied molecular or...

Absorption and fluorescence properties of oligothiophene biomarkers from long-range-corrected time-dependent density functional theory.

Journal: :Physical chemistry chemical physics : PCCP 2009

Bryan M Wong Manuel Piacenza Fabio Della Sala

The absorption and fluorescence properties in a class of oligothiophene push-pull biomarkers are investigated with a long-range-corrected (LC) density functional method. Using linear-response time-dependent density functional theory (TDDFT), we calculate excitation energies, fluorescence energies, oscillator strengths, and excited-state dipole moments. To benchmark and assess the quality of the...

Design of oligothiophene-based tetrazoles for laser-triggered photoclick chemistry in living cells.

Journal: :Chemical communications 2013

Peng An Zhipeng Yu Qing Lin

A 405 nm light-activatable terthiophene-based tetrazole was designed that reacts with a fumarate dipolarophile with the second-order rate constant k2 exceeding 10(3) M(-1) s(-1). The utility of this laser-activatable tetrazole in imaging microtubules in a spatiotemporally controlled manner in live cells was demonstrated.

Mechanical Response and Energy-Dissipation Processes in Oligothiophene Monolayers Studied with First-Principles Simulations

2010

Wojciech Kamiński Rubén Pérez

We present an extensive first-principles study of the interaction between a silicon oxide nanoasperity and a sexithiophene monolayer in order to investigate the individual molecular processes responsible for the energy dissipation during atomic force microscope (AFM) operation. Our approach includes not only ground-state calculations of the tip–sample interaction, but an extensive set of molecu...

Organic thin film transistors from a soluble oligothiophene derivative containing thermally removable solubilizing groups.

Journal: :Journal of the American Chemical Society 2004

Amanda R Murphy Jean M J Fréchet Paul Chang Josephine Lee Vivek Subramanian

A symmetrical alpha,omega-substituted sexithiophene derivative containing thermally removable branched ester solubilizing groups has been prepared. These oligomers can be solution cast into thin films and then thermolyzed to remove the solubilizing group, leaving short pendant alkene groups on the oligomer. Device testing of thin film transistors shows an increase in hole mobility from 1 x 10-5...
