The development of multiresponsive photochromic materials is of increasing interest for their potential application in the complicated chem. and biol. environment. Here, a novel D-A type dithienylethene derivative NDM, in which dimethylamino group acted as both electron donor (D) and recognition moiety for H⁺, and the dicyanovinyl group functioned as electron acceptor (A) and responsed to cyanide anion, has been designed and synthesized. Its structure was confirmed by ¹H NMR, ¹³C NMR and HRMS (ESI). As expected, dithienylethene NDM exhibited distinctive multi-modulated photochromic properties by solvent, acid and cyanide anion stimulation. Moreover, NDM can be acted as a potential fluorescent turn-on pH-sensor and colorimetric sensor for CN^– in biol. field.

Constructing and tuning self-organized 3-dimensional (3D) superstructures with tailored functionality is crucial in the nanofabrication of smart mol. devices. A self-organized, phototunable 3D photonic superstructure was fabricated from monodisperse droplets of 1-dimensional cholesteric liquid crystal (CLC) containing a photosensitive chiral mol. switch with high helical twisting power. The droplets are obtained by a glass capillary microfluidic technique by dispersing into PVA solution that facilitates planar anchoring of the liquid-crystal mols. at the droplet surface, as confirmed by the observation of normal incidence selective circular polarized reflection in all directions from the core of individual droplet. Photoirradiation of the droplets furnishes dynamic reflection colors without thermal relaxation, whose wavelength can be tuned reversibly by variation of the irradiation time. The results provided clear evidence on the phototunable reflection in all directions.

Zheng, Zhi-gang published the artcileThree-dimensional control of the helical axis of a chiral nematic liquid crystal by light, Name: 5-Chloro-3-[2-(5-chloro-2-methylthien-3-yl)cyclopent-1-en-1-yl]-2-methylthiophene, the publication is Nature (London, United Kingdom) (2016), 531(7594), 352-356, database is CAplus and MEDLINE.

Chiral nematic liquid crystals – otherwise referred to as cholesteric liquid crystals (CLCs) – are self-organized helical superstructures that find practical application in, for example, thermog., reflective displays, tuneable color filters and mirrorless lasing. Dynamic, remote and three-dimensional control over the helical axis of CLCs is desirable, but challenging. For example, the orientation of the helical axis relative to the substrate can be changed from perpendicular to parallel by applying an alternating-current elec. field, by changing the anchoring conditions of the substrate, or by altering the topog. of the substrate’s surface; sep., in-plane rotation of the helical axis parallel to the substrate can be driven by a direct-current field. Here we report three-dimensional manipulation of the helical axis of a CLC, together with inversion of its handedness, achieved solely with a light stimulus. We use this technique to carry out light-activated, wide-area, reversible two-dimensional beam steering-previously accomplished using complex integrated systems and optical phased arrays. During the three-dimensional manipulation by light, the helical axis undergoes, in sequence, a reversible transition from perpendicular to parallel, followed by in-plane rotation on the substrate surface. Such reversible manipulation depends on exptl. parameters such as cell thickness, surface anchoring condition, and pitch length. Because there is no thermal relaxation, the system can be driven either forwards or backwards from any light-activated intermediate state. We also describe reversible photocontrol between a two-dimensional diffraction state, a one-dimensional diffraction state and a diffraction ‘off’ state in a bilayer cell.

The development of stimuli-responsive difluoroboron β-diketonate materials has attracted more and more attention for their potential application in optoelectronics and functional bio-materials. In this study, we have designed and synthesized a novel photoresponsive dithienylethene-containing difluoroboron β-diketonate complex 1 by Knoevenagel condensation reaction.

And it exhibited solvent-dependent photophys. properties in solution before visible light irradiation Subsequently, photochromism of 1 was investigated in solution, and it was found that 1 revealed solvent-dependent and visible light-triggered NIR photochromic behaviors. Moreover, it also displayed excellent fluorescence switching behavior and photochromism in the film state upon visible light irradiation Accordingly, the dithienylethene 1 may be acted as a novel visible light-responsive fluorescence dyes in optoelectronic materials.

Wang, Sheng published the artcileA photochromic fluorescent probe for Hg2+ based on dithienylethene-rhodamine B dyad and its application in live cells imaging, Formula: C15H14Cl2S2, the publication is Science of Advanced Materials (2017), 9(3/4), 533-540, database is CAplus.

A new photoswitchable fluorescent mol. probe based on photochromic dithienylethene-rhodamine B dyad was designed and synthesized successfully. The dithienylethene-rhodamine B dyad exhibited excellent photochromism with reversible color changes upon photo-irradiation Upon addition of Hg2+, its color changed from colorless to red, and its fluorescence was remarkably enhanced; whereas, other ions including K+, Na+, Ag+, Ca2+, Mg2+, Fe2+, Co2+, Ni2+, Cu2+, Zn2+, Mn2+, Pb2+, Ni2+, Fe3+, Al3+, and Cr3+ induced basically no colorimetric and fluorescent color changes, which constituted a highly selective and sensitive fluorescent probe toward Hg2+. In addition, it exhibits unique fluorescent switching characteristics that can be controlled by Hg2+ and light stimuli. More importantly, by means of cells imaging experiments, it is demonstrated that this probe can enter living cells as a Hg2+ detector and respond to light stimuli, which shows its value for potential application in biol. systems.

The activity of the metabolic branch-point enzyme PriA from Mycobacterium tuberculosis (mtPriA) can be controlled reversibly by light. Two-pronged inhibitors based on the dithienylethene scaffold were designed utilizing mtPriA’s natural rotational symmetry. Switching from the flexible, ring-open to the rigid, ring-closed isomer reduces inhibition activity by one order of magnitude.

The polymerization of terthiophene to obtain an alkene bridged α,α-coupled sexithiophene polymer, was controlled by light; i.e., the electropolymerizability of the bis-terthiophene monomer is switched off and on upon illumination with UV and visible light, resp. The system comprises both bis-terthiophene and photochromic dithienylethene units. The presence of a light-switchable unit allows on-off switching of the electropolymerization of the monomer with light. The incorporation of dithienylethene in the backbone increases dramatically the homogeneity of the polymer formed (i.e., only sexithiophene units are formed). The films are robust and fully retain electrochromism as was demonstrated through cyclic voltammetry while spatial control (patterning) is readily achieved by applying simple optical masking techniques.

Rotaxanes have attracted much attention because of their challenging constructions and potential applications. In this paper, a multi-state [2]rotaxane, in which a dithienylethene-functionalized dibenzo-24-crown-8 macrocycle was interlocked onto a thread component bearing a 4-morpholin-naphthalimide fluorescent stopper and two distinct recognition sites, namely, dibenzylammonium and N-methyltriazolium recognition sites, was prepared and studied. By introducing a dithienylethene photochrome into the macrocycle component, multi-mode alteration of the intercomponent interactions, such as energy transfer, electron transfer, and charge transfer interaction between the photochrome and the fluorescent naphthalimide stopper could be altered in this multi-state rotaxane system in response to the combination of chem. and photochem. stimuli.
