Abstract: Cellulose nanocrystals (CNCs)-derived photonic materials have confirmed great potential in producing renewable optical and engineering areas. However, it remains challenging to simultaneously possess toughness, strength, and multiple responses for developing high-performance sensors, intelligent coatings, flexible…

Abstract: Abstract Five novel cationic cyclometalated Ir(III) complexes of type [(CˆC)IrX(PPh3)2(dmbpy)]A (X = halogen; dmbpy = 4,4′-dimethoxy-2,2′-bipyridine; A = counterion) were synthesised and characterised. Complexes 1–3 ([(CˆC)IrCl(PPh3)2(dmbpy)]A) have different anions (A = Cl−, CF3SO3−, PF6−) and complexes 4–5 ([(CˆC)IrX(PPh3)2(dmbpy)]PF6) have different halogen ligands (X = Br−,…

Abstract: Abstract Mechanochromic luminescent (MCL) materials have attracted great attention in the fields of sensing, memory chips, and anti-counterfeiting. However, most MCL materials only display a two-color change and it is challenging to achieve multicolor mechanochromism…

Abstract: We investigated conditions to prepare cellulosic cholesteric liquid crystalline (ChLC) films in order to accomplish dual mechanochromism, i.e., colour control and circular dichroic inversion upon mechanical stimulus, at room temperature. Flexible propionylated hydroxypropyl cellulose (PHPC)…

Abstract: Strong intermolecular interactions that are in favour of elevating the luminescence efficiencies of aggregation-induced emission luminogens (AIEgens) are usually detrimental to the generation of obvious mechanochromism (MC). Therefore, it remains a challenge to develop MC-active…

Abstract: Controlled polymer mechanochromism has large potential for new applications. We design a novel ESIPT mechanophore (HBIA-2OH) by three-step synthesis. Connected to polyurethane, it shows unique photo-gated mechanochromism from excited-state intramolecular proton transfer (ESIPT) via photo-induced…

Abstract: Photonic crystal slabs (PCS) are a promising platform for optical biosensing. Yet, flexible applications based on PCS for biosensing have been limited, as the mechanical properties influence the optical ones. Here, we show the suppression…

Abstract: Modulating the stimulus-responsiveness of a luminescent crystal is challenging owing to the complex interdependent nature of its controlling factors, such as molecular structure, molecular conformation, crystal packing, optical properties, and amorphization behavior. Herein, we demonstrate…
