Abstract Polymerized small molecule acceptors have recently greatly facilitated the development of all‐polymer solar cells (All‐PSCs) with respect to power conversion efficiencies (PCEs). However, high‐performance and low‐cost polymer donors for All‐PSCs are still lacking, limiting further large‐scale manufacturing All‐PSCs. Herein, this work designs synthesizes a new thiophene derivative, FETVT, featuring vinyl‐bridged fluorine ester‐substituted monothiophene. Incorporation FETVT into...
Abstract The carbon–carbon triple bond (–C≡C–) is an elementary constituent for the construction of conjugated molecular wires and carbon allotropes such as carbyne graphyne. Here we describe a general approach to in situ synthesize –C≡C– on Cu(111) surface via homo-coupling trichloromethyl groups, enabling fabrication individual arrays poly( p -phenylene ethynylene) wires. Scanning tunneling spectroscopy reveals delocalized electronic state extending along these wires, whose structure...

Abstract Biexcitons are a manifestation of many-body excitonic interactions, which crucial for quantum information and computation in the construction coherent combinations states. However, due to their small binding energy low transition efficiency, most biexcitons conventional semiconductors exist either at cryogenic temperatures or under femto-second pulse laser excitation. Herein, we demonstrated strong biexciton emissions from CsPbBr 3 nanoplatelets with continuous-wave excitation room...
