New method for the synthesis of a highly-conjugated acene material and its application in Perovskite solar cells

Abstract

Kita-type coupling and Scholl-type oxidative cyclodehydrogenation to afford acene from binaphthalene and mesitylene is as an effective alternative to the reported approaches.

Performance Enhancement of Inverted Perovskite Solar Cells Based on Smooth and Compact PC61BM:SnO2 Electron Transport Layers

“…Moreover, Huang et al applied graphdiyne − to modify PC 61 BM and improved the film conductivity and interfacial coverage of ETL . Jia et al employed acene to modified PC 61 BM and a PCE of 17.07% could be achieved . Lin et al reported that indene-C 60 bisadduct was employed to replace PC 61 BM for its higher LUMO level and a high PCE of 18.5% could be obtained .…”

“…Then, the prepared precursors 175a and 175b were subjected to reaction with FeCl 3 (oxidant and Lewis acid) to form promising products 176a and 176b in good yields ( Scheme 74 ). 105 …”

Recent progress in organometallic porphyrin‐based molecular materials for optical sensing, light conversion, and magnetic cooling

“…The thermodynamic possibility of the electron transfer in dyads with a MPX/MPcX donor part was evaluated using a ΔG CS parameter (the free-energy change for charge separation) that was obtained by cyclic voltammetry for (ImF)CoPc(3,5-di-t BuPhO) 8 /(AcO)(ImF) MnPc(3,5-di-t BuPhO) 8 and (PyF) 2 CoP (2,3,7,8,12,18)hexa-Me-13,17-di-Et-5-(Py-2-yl) in the 0.1 M (n-Bu) 4 NClO 4 solution in dichloromethane. [117,120] The corresponding ΔG CS values are −0.22/−0.07 and −0.72 eV.…”

“…The design and preparation of new conjugated molecules is one of the research topics in the science of molecular materials developed firstly as chemical physics of molecular conducting materials and then expanded on molecular optoelectronics and bioelectronics. [1][2][3] A planar structure and an ideal aromatic system are inherent in porphine molecules and their numerous derivatives. However, of great interest for the application as molecular materials are porphyrins predominantly in the form of metal derivatives due to the advent of new unique properties by the combination of metal atom and macrocycle electronic systems in one molecule.…”
