Electron-transporting semi-rigid polyester-imides composed of a tetracarboxdiimide (2,5-di(3,4-dicarboxphthalimido)-1,3,4-oxadiazole; DDPOD) of p-terphenyl analog of 1,3,4-oxadiazole were successfully prepared by the melt polycondensation of a monomer, a dialc. derivative of DDPOD, with four diesters in the presence of zinc acetate as a catalyst, and their thermal, UV-vis absorption, photoluminescent (PL) and electrochem. properties were examined The structures of the resulting polymers were characterized by Fourier transform IR and 1H NMR spectroscopies and elemental analyses. Differential scanning calorimetry measurements, X-ray diffraction analyses and polarizing microscope observations suggested that the polymers prepared from aliphatic diesters formed highly ordered thermotropic liquid crystalline smectic phases. The UV-vis and PL spectra in the solutions and in the films displayed that the obtained polymers showed absorption and bluish violet-light emissions based on the DDPOD moiety. Cyclic voltammetry measurements revealed that these polymers had more stable HOMO levels and were more sensitive to oxidation than polymers comprising electron-accepting 2,5-diphenyl-1,3,4-oxadiazole in the backbones. The DDPOD unit brought the extension of differences between electron-injection and hole-injection barriers in the polymers. It was found that the polymers containing the DDPOD unit in the main chains in this study not only showed bluish violet light-emitting properties but also behaved as electron-transporting materials for organic electroluminescent devices. 婕?2012 Wiley Periodicals, Inc.

Dimethyl decanedioate (cas: 106-79-6) belongs to esters. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Polyesters are important plastics, with monomers linked by ester moieties. Cyclic esters are called lactones, regardless of whether they are derived from an organic or inorganic acid. One example of an organic lactone is 绾?valerolactone.Application of 106-79-6
