An Air‐Stable Semiconducting Polymer Containing Dithieno[3,2‐b:2′,3′‐d]arsole

N-Benzoyl dithieno[3,2-b:2′,3′-d]pyrrole-based hyperbranched polymers by direct arylation polymerization

BACKGROUND Although poly(N-acyl dithieno[3,2-b:2',3'-d]pyrrole)s have attracted great attention as a new class of conducting polymers with highly stabilized energy levels, hyperbranched polymers based on this monomer type have not yet been studied. Thus, this work aims at the synthesis of novel hyperbranched polymers containing N-benzoyl dithieno[3,23,2-b:2',3'-d]pyrrole acceptor unit and 3-hex...

Design and synthesis of a new class of photochromic diarylethene-containing dithieno[3,2-b:2',3'-d]pyrroles and their switchable luminescence properties.

Bis(μ-dithieno[3,2-b:2′,3′-d]thio­phene-2,6-dicarboxyl­ato-κ2 O 2:O 6)bis­[bis­(1,10-phenanthroline-κ2 N,N′)cobalt(II)] dimethyl­formamide disolvate

The asymmetric unit of the title compound, [Co(2)(C(10)H(2)O(4)S(3))(2)(C(12)H(8)N(2))(4)]·2C(3)H(7)NO, contains one half of the formula unit, with the rest generated by inversion. The cobalt ion sits in a slightly distorted octa-hedral environment and is ligated to four N atoms of two 1,10-phenanthroline molecules and to two O atoms of two dithieno[3,2-b:2',3'-d]thio-phene-2,6-dicarb-oxy-l-ate...

Organic Thin Film Transistors Incorporating Solution Processable Thieno[3,2-b]thiophene Thienoacenes

Bottom-gate bottom-contact organic thin film transistors (OTFTs) were prepared with four novel star-shaped conjugated molecules containing a fused thieno[3,2-b]thiophene moiety incorporated either in the core and/or at the periphery of the molecular framework. The molecules were soluble in CS₂, allowing for solution-processing techniques to be employed. OTFTs with different channel geometries w...

A low band gap co-polymer of dithienogermole and 2,1,3- benzothiadiazole by Suzuki polycondensation and its application in transistor and photovoltaic cells

reduction of steric hindrance between the solubilising alkyl groups and adjacent thiophene rings. The improved crystalline structure of PSBTBT resulted in a higher charge carrier mobility and improved solar cell performance in blends with fullerene derivatives. Low band gap co-polymers containing silafluorene, 40 dithieno[3,2-b:2′,3′-d]silole 7 and silaindacenodithiophene have recently demonstr...
