Circularly polarized luminescence (CPL) active materials, especially pure organic small molecules, have emerged as a subject of considerable interest because their unique property emitting circularly light directly...
Singlet fission has attracted great attention in recent years owing to the potential of enhancing photoenergy conversion efficiency through exciton multiplication. Herein, we designed tetracene dimers bridged by two regio-isomers,...
With a cyclic “belt”, non-fused ring acceptor CSO4TIC shows more desirable performance compared to its counterpart with conventional linear side chains.
Precise adjustment of the nanoscale morphology within active layers is crucial for optimizing photovoltaic performance all-small-molecule organic solar cells (ASM-OSCs), and halogen substituent strategy materials plays a vital role in development evolution. In this work, we systematically study series acceptor–donor–acceptor (A-D-A) type small-molecule donors by incorporating halogenation at thienyl benzo[1,2-b:4,5-b′]dithiophene (BDT-T) donor core unit named BSTR-F, BSTR-Cl, BSTR-Br. Such...
The hitherto unknown hexakis(halomethyl)-functionalized tribenzotriquinacenes (TBTQs)
Solid additives have drawn great attention due to their numerous appealing benefits in enhancing the power conversion efficiencies (PCEs) of organic solar cells (OSCs). To date, various strategies been reported for selection or design non-volatile solid additives. However, lack a general design/evaluation principles developing often results individual offering only one two efficiency-boosting attributes. In this work, we propose an integrated omnidirectional strategy designing By validating...
Traditionally, hot excitons or carriers generated in semiconductors were considered unfavourable for many applications, given that they may cause energy loss and device degradation.
Designing electron acceptor materials with A–D–A′–D–A type structure is an effective way to achieve high-performance and low-cost organic solar cells (OSCs). Currently, almost all the acceptors contain sp3-hybridized bridge carbon in their donor part (D), which makes it possible introduce bulky side chains inhibit excessive intermolecular aggregation. However, existence of will deteriorate photostabilities acceptors. Herein, named TPD-BT bearing a...
Abstract Solid additives have drawn great attention due to their numerous appealing benefits in enhancing the power conversion efficiencies (PCEs) of organic solar cells (OSCs). To date, various strategies been reported for selection or design non‐volatile solid additives. However, lack a general design/evaluation principles developing often results individual offering only one two efficiency‐boosting attributes. In this work, we propose an integrated omnidirectional strategy designing By...
This work presents the first demonstration of a mechanochromic organic micro-laser, which exhibits remarkable wide range pressure sensing characteristics. The gain material, pinacolato boronate ester functionalized anthanthrene (AnBPin), is designed by incorporating mechanofluorochromic (MFC) properties into laser dye. AnBPin reversible transition between green and orange fluorescence upon grinding annealing recrystallization cycle, its micro-crystal typical micro-laser behaviors. Applying...
