A new class of compounds known as chalcogenosilacyclopentanes is described. These compounds are five-membered ring structures containing a silicon-selenium or silicon-tellurium bond, as shown in Formulas (I) and (II). In these compounds, the substituents on the silicon and on the ring carbons may be hydrogen, alkyl, alkoxy, aromatic, or ether groups. The chalcogenosilacyclopentane compounds undergo ring-opening reactions with hydroxyl and other protic functionalities and may be used to prepare substrates that are amenable to thin film deposition techniques such as ALD and CVD. ##STR00001##

Surfactants for use in formulations and processes suitable for hydrocarbon recovery. These formulations, include formulations suitable for fracking, enhancing oil and or gas recovery, and the recovery and or production of bio-based oils.

Coordination complexes of tetrathiafulvalene-based dithiolene linkers, such as tetrathiafulvalene-2,3,6,7-tetrathiolate (TTFtt), and their oxidation products are described.
