چکیده
Cross-linked polymer films are prepared by the alternating copolymerization of 4-chloromethylstyrene and 7,7,8,8-tetracyanoquinodimethane comonomers, which is followed by the postfunctional surface modification with donor-acceptor chromophores or redox active components using click chemistry reactions.

Reactive, multifunctional polymer films through thermal cross-linking of orthogonal click groups.
The ability to produce robust and functional cross-linked materials from soluble and processable organic polymers is dependent upon facile chemistries for both reinforcing the structure through cross-linking and for subsequent decoration with active functional groups. Generally, covalent cross-linking of polymeric assemblies is brought about by the application of heat or light to generate highl...
متن کاملPhysical and electrical characteristics of supramolecular polymer films based on guanosine derivatives modified with tetrathiafulvalene moiety
Supramolecular films consisting of guanosine derivatives modified with a tetrathiafulvalene (TTF) moiety have been prepared. The hydrogen bonding network of the guanosine unit enables the formation of a robust and self-supporting cast film by a solution process. Differential scanning calorimetry and dynamic mechanical analysis (DMA) revealed that the self-supporting films were mechanically flex...

A series of donor-acceptor molecules, featuring intense low-energy intramolecular charge-transfer bands, was prepared by regioselective [2 + 2] cycloaddition between 7,7,8,8-tetracyanoquinodimethane (TCNQ) and N,N-dialkylanilino-substituted (DAA-substituted) alkynes, followed by ring opening of the initially formed cyclobutenes.
متن کاملSpectroscopy and dynamics of the 7,7,8,8-tetracyanoquinodimethane radical anion.
The photoelectron spectrum of the 7,7,8,8-tetracyanoquinodimethane (TCNQ) radical anion has been measured at 3.1 eV. Additionally, the ultrafast relaxation dynamics of the first excited state (1(2)B(3u)) of TCNQ(-) have been studied using time-resolved photoelectron spectroscopy, which reveals that it undergoes internal conversion back to the ground state ((2)B(2g)) with an associated lifetime ...
متن کاملIon insertion into individual 7,7,8,8-tetracyanoquinodimethane nanoparticles.
We report the quantification of partial ion insertion into individual 7,7,8,8-tetracyanoquinodimethane nanoparticles. It is shown that both potassium and sodium ions can be inserted into single TCNQ nanoparticles from aqueous solution. The extent of both potassium and sodium insertion into individual nanoparticles is quantitatively measured and shown to be partial and sodium ion shows a higher ...
