TL;DR: In this paper, a ladder-type electron-deficient core-based central fused ring (Dithienothiophen[3.2-b]- pyrrolobenzothiadiazole) with a benzothiadiadiazoles (BT) core was proposed to fine-tune its absorption and electron affinity.

TL;DR: In this article, a new member of the Y-series acceptor family, Y18, was designed and synthesized, which adopts a fused benzotriazole segment with unique luminescence properties as its electron-deficient core.

TL;DR: A new n-OS acceptor, Y5, with an electron-deficient-core-based fused structure is designed and synthesized, which exhibits a strong absorption in the 600-900 nm region with an extinction coefficient of 1.24 × 105 cm-1 and an electron mobility of 2.11 × 10-4 cm2 V-1 s-1, which indicates that Y5 is a universal and highly efficient n- OS acceptor for applications in organic solar cells.

TL;DR: This is the first time to synthesize mutifused benzotriazole-based molecules as nonfullerene electron acceptor as well as the recently synthesized hexafluoroquinoxaline-based polymer HFQx-T as donor.

TL;DR: In this paper, a small molecule, ITTC, bearing an indacenodithieno[3,2-b]thiophene core and a 2-(6-oxo-5,6-dihydro-4H-cyclopenta[c]-thiophen-4-ylidene)malononitrile end group, was designed, synthesized and characterized as a non-fullerene electron acceptor.
