In summary, we have prepared new mol. constructs composed of electron-donating tetrathiafulvalene (TTF) and p-extended-TTF derivatives covalently connected to electron-accepting pyrrolidino[3,4:1,2] fullerene through photo-switchable dithienylethene bridges. By exposure to a light stimulus the bridge can be interconverted between a decoupled ring-open and a coupled ring-closed form and, hence, enables external control of electronic communication between the donor and acceptor units. In the resulting architectures, incoming photons give rise to efficient charge separation and, furthermore, allow modulation of the lifetimes of the charge-separated states over two orders of magnitude by variation of their wavelength. The photoresponsive, dynamic bridge provides a means for (self-)regulation through a reversible activation-deactivation mechanism for solar energy conversion in artificial photosynthetic systems.

There is continuing interest in the design and synthesis of functional materials for applications in mol. electronics and information storage. Of particular interest are systems that can provide multiple means for controlling transport through well-defined and stable electronic and/or redox states. The authors report herein the synthesis and characterization of a system containing transition-metal complexes along with dithienylethene (DTE) units so as to achieve photo and redox control of transport. A facile synthetic methodol. was developed to assemble and couple metal terpyridine (M-tpy) complexes with the photochromic DTE unit in a linear structure with M-DTE-M or DTE-M-DTE arrangements, with emphasis on the latter series. The photochromic properties of these assemblies were examined by monitoring the changes in their UV/visible spectra upon irradiation at specific wavelengths capable of triggering the open/closed isomerization in the DTE units. Their electrochromic properties were studied via cyclic voltammetry and controlled potential electrolysis experiments Complexes 10 (PhDTE-Fe-DTEPh) and 11 (PhDTE-Co-DTEPh) with phenyl-ending groups are both photochromic and electrochromic, so they represent excellent candidates for further elaborations. The Fe(II)-containing complex 8 (ClDTE-Fe-DTECl) with chloride-ending groups was photochromically inactive but could undergo the electrochem. induced open-to-closed isomerization. On the contrary, the electrochromically inactive complex 9 (ClDTE-Co-DTECl) underwent cyclization under UV irradiation

Dinuclear metal terpyridine (M-tpy; M = Ru, Os, Fe, and Co) complexes with a photochromic dithienylethene bridge were designed and synthesized through either a convergent or a divergent approach. The open forms of the complexes containing Ru^II and Fe^II centers are inert to UV photoirradiation but could be cyclized electrochem. as revealed by a cyclic voltammetric study. On the contrary, the Co^II complex underwent efficient photochem. but not electrochem. cyclization. The corresponding Os^II complex was neither photochromic nor electrochromic.

A two-step Ir-catalyzed borylation/Pd-catalyzed dehalogenation sequence allows for the net synthesis of fluoroarenes where the boronic ester is ortho to fluorine. Key elements of this approach include the use of a halogen para to the fluorine to block meta Ir-catalyzed borylation and the chemoselective Pd-catalyzed dehalogenation by KF activated polymethylhydrosiloxane (PMHS).

Adding external, remote, and dynamic control to self-organized superstructures with desired properties is an important leap necessary in leveraging the fascinating mol. subsystems for employment in applications. Here two novel light-driven dithienylethene chiral mol. switches possessing remarkable changes in helical twisting power during photoisomerization as well as very high helical twisting powers were found to experience photochem. reversible isomerization with thermal stability in both isotropic organic solvents and anisotropic liquid crystal media. When doped into a com. available achiral liquid crystal host, the chiral switch was able to either immediately induce an optically tunable helical superstructure or retain an achiral photoresponsive liquid crystal phase whose helical superstructure was induced and tuned reversibly upon light irradiation Moreover, reversible light-directed red, green, and blue reflection colors with thermal stability in a single thin film were demonstrated.

Li, Yannian published the artcileSynthesis and Characterization of Light-Driven Dithienylcyclopentene Switches with Axial Chirality, Recommanded Product: 5-Chloro-3-[2-(5-chloro-2-methylthien-3-yl)cyclopent-1-en-1-yl]-2-methylthiophene, the publication is Journal of Organic Chemistry (2011), 76(17), 7148-7156, database is CAplus and MEDLINE.

Dithienylcyclopentenes such as I and its enantiomer were prepared as photochem. reversible but thermally stable switches with axial stereochem. All three compounds prepared exhibited photochem. reversible isomerization between their open forms and closed forms and were thermally stable in the open and closed forms both in organic solvents and in a liquid crystal host. Dithienylcyclopentenes such as I acted not only as chiral dopants, inducing helical superstructures in achiral liquid crystal hosts, but also reversibly and dynamically tuned the transmittance and reflection of the resulting chiral phases upon light irradiation The helical twisting powers, transmittance, and reflection spectra of photoswitchable cholesteric liquid crystals were measured. I exhibited an unusually high helical twisting power, which is significantly larger than those of the known chiral diarylethenes reported as chiral dopants so far.

Three thermally irreversible photochromic chiral liquid crystal dithienylcyclopentenes were found not only to be able to self-organize into a phototunable helical superstructure, i.e., cholesteric phase, but also to be able to induce a photoresponsive helical superstructure in an achiral liquid crystal host. The cholesteric phase in the three chiral compounds went into a glassy phase without crystallization upon cooling. All the materials exhibited reversible photochromism with thermal stability in both solution and thin film, and their fluorescence was shifted to longer wavelength upon UV irradiation while the shifted fluorescence was recovered upon visible light irradiation The enhanced fluorescence emission with the addition of fluoride anions was observed, and its reverse process happened with the addition of an equivalent proton.
