Polv(ether) Synthesis. The poly(ethers) were made by a two-phase reaction with dibromoalkanes. In a typical reaction, 0.75 g (2.4 mmol) of (II, R=H)) was mixed with 70 ml of 2N NaOH in a 3-necked round-bottom flask equipped with a mechanical stirrer. To this was added an equimolar amount of 1,9-dibromononane in 20 mL nitrobenzene and approximately 10 mg of tetrabutylammonium iodide and the mixture was stirred overnight at 50°C. The resulting solid mass was washed with methanol and then with 2N NaOH. After washing with 0.1 N HC1, the product was Soxhlet-extracted with methanol and dried to yield 0.68g (64.7%) of a light green powder which melted to an anisotropic liquid at 290°C. The other poly(ethers) were prepared in the same manner, using spacer lengths of 7, 9,11, 7/9 mixture, and 9/11 mixture. The yields and IR spectra of the poly(ethers) is shown in Table I.

Shi et al. [70] were the first to demonstrate the use of an air and moisture stable ionic liquid, [C4mim][PF,s], for the electrochemical synthesis of poly(thiophene), grown onto a platinum working electrode by potentiodynamic, constant potential or constant current techniques. The use of growth potentials between 1.7 and 1.9 V (vs. Ag/AgCl) reportedly gave smooth, blue-green electroactive films, whereas potentials above 2 V resulted in film destruction by overoxidation.

Synthesis Poly(para-phenylene vinylene) (PPV, XI) is the archetypical fluorescent polymer. It emits a bright green-yellow light with two emission peaks at 520 nm (2.38 eV) and 550 nm (2.25 eV). Direct synthesis of XI yields an intractable,... 

In the synthesis of the nonamethoxy-l-pentacosene (622), a naturally ocurring poly-methoxy-l-alkene isolated from the blue-green alga Tolypothrix conglutinata var. chlorata, the backbone is assembled using two aldehydes (620 and 621) (Scheme 91) [146].
