High-performance, low-voltage organic field-effect transistors using thieno[3,2-b]thiophene and benzothiadiazole co-polymers

Abstract

A series of new linear conjugated polymers incorporating different substituted thieno[3,2-b]thiophenes as donor, acetylene as π-bridge and benzothiadiazole as acceptor units were synthesized via Pd-catalyzed Sonogashira cross-coupling polymerization.

Cationic and radical polymerization using a boron–thienothiophene–triphenylamine based D–π–A type photosensitizer under white LED irradiation

“…[23][24][25][26][27][28] It is an electron-rich molecule, making it a promising material for the construction of conjugated and low band gap polymeric semiconductors for electronic and optical applications such as electroluminescence, two-photon absorption, excited fluorescence, photochromism. [29][30][31][32][33][34][35] Triphenylamine (TPA) is a classical and well-known example of the triarylamine family, having an ionization potential of 6.80 eV , which is lower than several inorganic and organic molecules. [36][37][38][39] It makes TPA a strong electron-donating unit in both conjugated small molecules and polymeric materials.…”

Synthesis and characterization of naphthalenediimide-thienothiophene-conjugated polymers for OFET and OPT applications

“…Over the years, state-of-the-art polymer-based organic semiconductors have improved extensively due to the number of unique features in electronic applications such as organic photovoltaic cells (OPVs), 1,2 organic field-effect transistors (OFETs), [3][4][5][6] organic light-emitting diodes (OLEDs) [7][8][9][10][11] and memory devices. 12,13 Among the organic and printable electronics, great success has been achieved with OFETs, including flexible displays, photonic sensors and artificial skin.…”

Thieno[3,2-b]thiophene and triphenylamine-based hole transport materials for perovskite solar cells

“…Thieno[3, thiophene, in particular, is the most conjugated and stable isomer of TTs, having interesting electronic and optical properties. It has been examined and used in various energy-based organic electronic applications by our group such as OLED (Isci et al, 2020a;2022a), OFET (Amna et al, 2022), electrocatalyst (Isci et al, 2022d), capacitor (Topal et al, 2021), andmemory (Gunturkun et al, 2022).…”
