The electrochemical and chemical syntheses of poly(terthiophene)s bearing an indanedione pendant group and displaying intramolecular charge transfer interactions have been achieved. The nature of the charge transfer interaction is characterized through DFT calculations and experimental studies, including resonance Raman spectroscopy and absorption and emission data through a Lippert-Mataga analysis. It is found that the low-energy transition present in the indanedione-bearing monomer species has considerable charge transfer character with a dipole change of II D. Decomposition of the indanedione group occurred during hydrazine reduction after chemical polymerization. A soluble, low molecular weight indanedione-substituted polymer (weight average 4500 Da) was nonetheless obtained …

Two 6 GHz microstrip patch antennas made from conducting polymers with relatively low DC conductivity such as PEDOT (10000 S/m) and PPy (2000 S/m) are presented. The performance of these patch antennas is compared with a similar copper patch antenna. The results indicate that it is possible to obtain reasonable performance albeit with modest radiation efficiencies. The PEDOT antenna achieved a maximum gain of 2.2 dB, while the PPy antenna reached a gain of 3.8 dB, as against 6.0 dB for a corresponding Cu patch antenna The results confirm the potential of polymer materials for microwave antennas and suggest that …
