Isothermal crystallization and time-temperature-transformation diagram of the organic semiconductor 5,11-bis(triethylsilylethynyl)anthradithiophene

Abstract

Thermal annealing of organic semiconductors is critical for optimization of their electronic properties. The selection of the optimal annealing temperature –often done on a trial-and-error basis– is essential for achieving...

Constructing two-dimensional crossed molecular packing through branching chain engineering of amino-indenofluorene derivatives

“…46,47 In addition, the changes in the film nanostructure can modify the relatively deep trap environment and result in a more negative threshold voltage. 48,49 The as-deposited EOA-IFD film shows the maximum hole mobility of 9.20 × 10 −4 cm 2 V −1 s −1 , while the maximum mobility is promoted to about 5 × 10 −3 cm 2 V −1 s −1 by treating at 60–100 °C. The increase in mobility of the EOA-IFD film suggests that the γ-phase EOA-IFD may facilitate higher carrier mobility.…”

Following the crystal growth of anthradithiophenes through atomistic molecular dynamics simulations and graph characterization

“…There has been a longstanding effort to understand how the molecular chemistry of the OSC building blocks and processing methods impact the nucleation, growth, and order – including designs to either increase or suppress crystallization – of the resulting thin film. 24–37 From a modeling perspective, exploring these connections requires combinations of techniques that cover multiple length and temporal scales, with atomistic and coarse-grained molecular dynamics (MD), kinetic Monte Carlo, and microscopic thermodynamics models being developed for these purposes. 30,38–48 While these modeling investigations are non-trivial, they can provide physically meaningful insight into these processes at experimentally relevant scales.…”
