Synthesis and Intramolecular Charge-Transfer Interactions of a Donor–Acceptor Type Polymer Containing Ferrocene and TCNAQ Moieties

Vice versa donor acceptor fluorene–ferrocene alternate copolymer: a twisted ribbon for electrical switching

“…In PFFC-2, one strong reduction at E1/2 red -1.52 V is ascribed to the cyanofluorene anion formed owing to intramolecular charge transfer from donor Fc to accepter cyanofluorene unit. 17 The scan rate dependent cyclic voltammetry studies (ESI †, Fig. S5a-b) and linearity of the plot (ESI †, Fig.S6a-b) and 8.7×10 -9 cm 2 /s for PFFC-1 and PFFC-2, respectively which are consistent to the previously reported data of this type main chain ferrocene copolymer.…”

Synthesis and characterization of conjugated polymer based on tetracyano-anthraquinodimethane

“…The weak absorption in the wavelength between 520-780 nm is due to intra-molecular charge transfer (ICT) between the donor and acceptor moieties in polymer. The absorption maximum of the PTCAQ-BDT polymer solution was significantly red-shifted to about 100 nm compared with that of the previously reported TCAQ-based polymer [11]. The red-shift is due to better conjugation and strong ICT in PTCAQ-BDT.…”

“…However, the conjugated polymers containing TCAQs as acceptors are under-developed so far. The only reported polymer based on TCAQ unit was synthesized by Staudinger reaction [11]. The synthesis and novel structure of that polymer were interesting.…”

“…In the early study on TCAQ-based polymer, it has been suggested that the tetracyano groups in TCAQ tended to form complexes with the palladium atoms which are used as metal catalysts in polymerization reactions [11]. As a result, the palladium catalysts lost their effectiveness.…”

Porous Carbons – Hyperbranched Polymers – Polymer Solvation

“…Co-pyrolysis with other wastes such as food wastes is also plausible. Much work has been carried out on other pressurized carbonization methods such as biomass hydrothermal carbonization [111,112]. If an industrial process is to emerge from the research, the combined use of various carbon sources would be attractive for economy-of-scale purposes.…”
