An organic compound represented by the following general formula (I) and characterized by the conjugation of thieno[3,2-b]thiophene, thiophene and phenylene units in the conjugated compound. 

Thienothiophene derivatives

A novel conjugate of a support material and an oligomer or polymer of a saccharide that is linked to the support material via urea linkages, and in which the oligomers or polymers are cross-linked via urea linkages provides a valuable stationary phase for chromatography. It is particularly valuable as a chiral stationary phase in enantiomeric separations and enantiomeric analysis.

Saccharide and support for chromatography

The present invention relates to poly(arylene ethers) used as low k dielectric layers in electronic applications and articles containing such poly(arylene ethers) comprising the structure: wherein n=5 to 10000 and monovalent Arand divalent Arare selected from a group of heteroaromatic compounds that incorporate O, N, Se, S, or Te or combinations of the aforesaid elements, including but not limited to:

Materials comprising saccharide cross-linked and chemically bonded to a support via urea linkages

Novel and improved chiral stationary phases (CSP) materials comprising a support and completely regiodefined derivitised cyclodextrin chemically bonded via single or double urethane linkage(s) universally applicable in HPLC, LC, TLC, and CCE are obtained using a process based on the almost quantitative reaction of pre-synthesized regiodefined per-functionalized mono- or di- azidocyclodextrin with primary amines.
