Although many examples of mechanically flexible crystals are currently known, their utility in all-flexible devices is not yet adequately demonstrated, despite immense potential for fabricating high performance devices. Here, we report two alkylated diketopyrrolopyrrole (DPP) semiconducting single crystals, one which displays impressive elastic mechanical flexibility whilst the other brittle. Using crystal structures and density functional theory (DFT) calculations, show that methylated...

Abstract Molecular ferroelectrics are of enormous interest due to their ease synthesis and simplicity in device fabrication. Here, the non‐volatile memory effect a polycrystalline thin film single‐component ferroelectric material naphthalene monoimide (NMI), 6‐bromo‐2‐(1‐phenylethyl)‐1H‐benzo[de]isoquinoline‐1,3(2H)‐dione ( NMI‐ R Bn ), obtained by introducing enantiomeric α‐methylbenzyl ) substituents on NMI backbone is demonstrated. Both S derivatives crystallized monoclinic P 2 1 space...
The dark-orange monomer single crystals of 1,1'-dioxo-1H-2,2'-biindene-3,3'-diyldidodecanoate (BIT-dodeca2) convert to a transparent single-crystalline polymer (PBIT-dodeca2) material via single-crystal-to-single-crystal (SCSC) polymerization reaction under sunlight, which then undergoes reverse thermal transformation into BIT-dodeca2 crystals, leading reversible photo-/thermochromism, coupled with mechanical actuation. We exploit the properties this unique demonstrate formation...
The solids salinazide (Slz) and 3-chloro-2-nitrobenzoic acid (CNB) are thermosalient (TS) in nature their single component forms; upon cocrystallization with pentafluorobenzoic (PNB) 4,4′-bipyridine (BPY), respectively, they produced a salt (Slz-PFB) cocrystal, CNB-BPY, which also TS nature. A detailed structural analysis of all the forms question is carried out to verify if solid that shows behavior its form can be used as template generate new multicomponent forms. study significant...
We report the solid-state structural properties and phase transition behavior of 1,4-dibromo-2,3,5,6-tetramethylbenzene, demonstrating that this material undergoes an order–disorder below ambient temperature (at ca. 154 K on cooling 160 heating). In both high-temperature low-temperature phases, crystal structure is based π-stacking molecules. phase, bromine occupancy in each substituent site 1/3 methyl group 2/3, consistent with statistical orientational disorder molecule between six...
Constructing smart mini-actuator devices with high efficiency and low cost using renewable energy are vital for future applications in various fields.In this context, molecular actuators that convert external into mechanical work visible light more attractive than UV due to the obvious reasons.In recent years research on conversion of form by photomechanical bending attracted great attention.Photoreaction highly ordered crystals such as cis-trans isomerisation, electrocyclic reaction,...
