چکیده
The molecular engineering of conjugated systems has proven to be an effective method for understanding structure–property relationships toward the advancement optoelectronic properties and biosensing characteristics. Herein, a series three thieno[3,4-c]pyrrole-4,6-dione (TPD)-based monomers, modified with electron-rich selenophene, 3,4-ethylenedioxythiophene (EDOT), or both building blocks (Se-TPD, EDOT-TPD, EDOT-Se-TPD), were synthesized using Stille cross-coupling electrochemically polymerized, their electrochromic applications in glucose platform explored. influence structural modification on electrochemical, electronic, optical, was systematically investigated. results showed that cyclic voltammograms EDOT-containing materials displayed high charge capacity over wide range scan rates representing quick propagation, making them appropriate high-performance supercapacitor devices. UV-Vis studies revealed EDOT-based presented wide-range absorptions, thus low optical band gaps. These two EDOT-modified also exhibited superior contrasts fast switching times, further multi-color neutral fully oxidized states, enabling promising constructing advanced In context applications, selenophene-containing polymer markedly lower performance, specifically signal intensity stability, which attributed improper localization biomolecules surface. Overall, we demonstrated relatively small changes structure had significant impact TPD-based donor–acceptor polymers.

A rapidly growing demand for networked information has stressed the need for effective ways of managing large amounts of complex data. While more traditional solutions such database technology are already playing a major role, it seems clear that the mismatch between the relational and object oriented paradigms will be exposed by some applications as a source of major inefficiency. The upside p...
متن کاملElectrochromic materials for electronic paper
Electrochromic materials have the possibility to change their colour reversibly when they are transformed in a differently charged state. By applying an external voltage, charged molecules move towards the electrodes where they accept or donate an electron, and obtain a different colour. When the external voltage is switched off, they return to their initial colour. Recently electrochromism has...
