As one of the most promising nonfullerene acceptors for organic photovoltaics, perylene diimide (PDI)-based multibranched molecules with twisted or three-dimensional (3D) geometric structures have been developed, which effectively increase power conversion efficiency (PCE) solar cells. Understanding structure–property relationships in multichromophoric molecular architectures at and ultrafast time levels is a crucial step establishing new design principles electronic materials. For this,...
Three novel perylene diimides featuring [1,2]dithiine and sulfur annulation onto the PDI core different branched alkyl chains have been designed facilely synthesized. The organic thin-film transistor (OTFT) devices based on as-synthesized compounds showed maximum electron mobilities of up to 0.008 cm2 V-1 s-1 under an ambient atmosphere.
This work reports a facile method to prepare pyran-annulated perylene diimides, which are used as photocatalysts in photocatalytic water splitting.
Abstract Three sulfur‐containing pyran‐annulated perylene diimides (PDIs) were synthesized from commercially available PDIs through a nucleophilic substitution/cyclization reaction sequence. The as‐synthesized compounds fully characterized by 1 H and 13 C NMR, FT‐IR spectroscopy, as well HRMS TGA. as‐prepared PDI derivatives exhibited significantly narrow HOMO–LUMO band gaps high photochemical thermal stability. Moreover, these materials quite different absorptions emissions in...
Nonfullerene electron acceptors (NFAs) improve the photoelectrical conversion efficiency of organic solar cells (OSCs), but they suffer from high synthetic cost and time‐consuming thermal annealing treatment. Nevertheless, low‐cost NFAs simple device fabrication are still crucial issues to boosting commercial application OSCs. Herein, one kind pentacyclic based on benzothiadiazole thiophene derivatives named L1‐EH L1‐BO with different substitutions is successfully synthesized characterized....
In 2021, the State Conference of Vocational Education proposed a series measures to accelerate construction process modern vocational education, including forming secondary vocational, higher and professional undergraduate education integration, deepening “three teaching” reform, “post-class competition” comprehensive education. view problems in development this paper presents strategy integration from aspects teachers, teaching materials, models students. Then, taking information technology...
Computer science major in secondary vocational schools focuses on cultivating students' ability to solve complex engineering problems. Thus both theoretical and practical teaching of professional courses are critically important. Due the rapid update knowledge computer domain, it is becoming challenging better integrate theory practice for with advanced intelligent information technology. This paper constructs graph networking course group schools. We first propose methods data acquisition,...
Mathematics extracurricular activities are not only conducive to students’ all-round development, but also a beneficial supplement the current classroom teaching. In this study, 30 pieces of literature on mathematics in middle school from 1993 2022 were selected database China Knowledge Network（CNKI) as data source. This paper qualitatively analyzed summarize and sort out previous research found that: (1) Current domestic studies mainly focus following four aspects: classification, forms...
