Usage

General Description

"(4,4'-didodecyl-2,2'-bithiophene-5,5'-diyl)bis(trimethylstannane)" is a complex chemical compound that possibly falls into the category of organometallic compounds due to the presence of metal (stannane which is a derivative of tin). Two key components in its structure are bithiophene and didodecyl. Bithiophene is a biothiophene derivative, implying the existence of sulfur atoms in its structure. Didodecyl possibly represents the presence of long carbon chains. The application or properties of this chemical is not commonly documented, which is routine for such specific and complex compounds. However, similar compounds are often used in the development or synthesis of other complex compounds, including polymers, in industries such as pharmaceuticals and chemical engineering.

High charge carrier mobility, low band gap donor-acceptor benzothiadiazole-oligothiophene based polymeric semiconductors

A series of benzothiadiazole oligothiophene and oligo(thienylene vinylene) donor-acceptor (D-A) copolymers were synthesized and characterized. These low optical band gap materials (～1.5 eV) are capable of absorbing photons in the range of 400-800 nm and exhibit good thermal stability. Their hole mobilities, determined using an organic field-effect transistor (OFET) architecture, vary over a range of 3 orders of magnitude and strongly correlate with the molecular ordering and morphology of the respective thin films. Spin-coated films of the poly(benzothiadiazole-sexithiophene) PBT6, which exhibits a highly crystalline lamellar π-π stacked edge-on orientation on the OFET substrate, possesses a hole mobility of ca. 0.2 cm2/V·s. Vinylene-containing analogs PBT6V2 and PBT6V2′ are amorphous and exhibit very low mobilities. The molecular weight of PBT6 has a strong influence on the electronic properties: a sample with a lower molecular weight exhibits a mobility approximately 1 order of magnitude lower than the high molecular weight homologue, and the absorption maximum is appreciably blue-shifted. The hole mobility of PBT6 is further enhanced by a factor of ca. 3 through fabrication of the OFET by drop casting. OFETs fabricated by this process exhibit mobilities of up to 0.75 cm2/V·s and ION/OFF ratios in the range of 106-107. These results demonstrate the potential of incorporating benzothiadiazole units into polythiophene derivatives to develop high-mobility semiconducting polymers.

The influence of electron deficient unit and interdigitated packing shape of new polythiophene derivatives on organic thin-film transistors and photovoltaic cells

A series of new polythiophene derivatives containing a thiazole ring as an electron deficient unit were successfully synthesized via Stille coupling reactions. Synthesized polymers were classified into two types (H-shape packing and A-shape packing) based on their interdigitated packing structure induced by different side chain configurations. The thiophene derivatives that contained a thiazole unit (PT50Tz50, PTz100, and PTTz) exhibited much better thermal stability than did the full thiophene polymers (PT100 and PTT). The polymers containing the thiazole unit (PTz100 and PTTz) showed a red-shifted absorption spectrum with clear vibronic structure. In addition, the XRD and AFM results showed that the polymers containing the thiazole unit and interdigitated H-shape exhibited much better ordered and connected intermolecular structures than did other polymers. The improved intermolecular ordering and surface morphologies directly facilitated charge carrier transport in thin film transistor (TFT) devices, without introducing charge traps, and yielded higher solar cell performance. Among these polymers, the PTTz copolymer exhibited the best TFT performance (μ = 0.050 cm2 V-1 s-1, on/off ratio = 106, and Vth = -2 V) and solar cell performance (PCE = 1.39%, Jsc = 6.58 mA cm-2, and Voc = 0.58 V).
