Among the topics are liquid gradient refractive index lenses, photorefractive polymers for three-dimensional display applications, optimal gene detection using conjugated polymers, polymer ion sensors based on intramolecular charge-transfer interactions, detecting explosives and metal ions using fluorescent polymers and their nanostructures, holographic polymer-dispersed liquid crystals: from materials and morphologies to applications, and polymer nanostructures through packing spheres.
However, the conventional techniques such as the electropolymerization or chemical polymerization uniformly make architectures with intertwisted molecular conformation can no longer form an interconnected network inside the nanodevices, which is highly desirable to reduce the electronic resistance to improve the conduction, electrochemical stability and also to achieve rapid charge-transfer kinetics [15], By addressing these issues, fabrication of well-defined mono-/multi-layers of PPy on electrode is of high importance [16, 17], The electrical performances, in particular, the extraordinary charge transfer by a tunneling mode is important for designing versatile electrical devices.

When the electron-accepting NDI chromophore is covalently or non-covalently bonded to an electron-donating group such as DAN the resulting complex tends to facilitate charge-transfer (C-T) induced donor-acceptor (D-A) stacking.

According to this point of view, the total charge-transfer QT from donor (D) to acceptor (A) should determine the energy of the donor-acceptor bond and, as a result, the complexation energy.
