TL;DR: In this article, a novel thiophene derivative, FE-T, featuring a monothiophene functionalized with both an electron-withdrawing fluorine atom (F) and an ester group (E), is presented.

TL;DR: It is demonstrated that fluorination of imide-functionalized arenes offers an effective approach for developing new electron-deficient building blocks with improved optoelectronic properties, and the emergence of f-FBTI2 will change the scenario in terms of developing n-type polymers for high-performance all-polymer solar cells.

TL;DR: A traditional anchoring group (2-cyanoacrylic acid) widely used in molecules for dye-sensitized solar cells is incorporated into donor-acceptor type HTMs to afford MPA-BT-CA, which enables effective regulation of the frontier molecular orbital energy levels and efficient defect passivation toward perovskite layer.

TL;DR: In this article, a general concept of catalysed n-doping of organic semiconductors using air-stable precursor-type molecular dopants is presented, where the incorporation of a transition metal (for example, Pt, Au, Pd) as vapour-deposited nanoparticles or solution-processable organometallic complexes, as assessed by experimental and theoretical evidence, enables greatly increased η in a much shorter doping time and high electrical conductivities.
