A general method for synthesizing inexpensive, renewable, non-toxic, non-fluorous, carbohydrate based CO 2 -philes is disclosed. These CO 2 -philes are soluble in carbon dioxide. Methods of making the composition are also disclosed. The methods and composition are useful in a variety of applications and can utilize gaseous, liquid and supercritical carbon dioxide. The methods and compositions are useful in the synthesis of surfactants and metal chelates for CO 2 , as a sizing substrate, in CO 2 -based coating processes, for impregnation and plasticizing cellulosic and non-cellulosic materials, in pharmaceutical applications, such as crystallization, dispersion and encapsulation of bioactive molecules in solid systems, in the densification of CO 2 , in the synthesis of biodegradable polymers in CO 2 , and for carbon dioxide removal, to name just a few.

专利号:US-8889334-B2 优先权日:2001-11-15 标题:Spin-on anti-reflective coatings for photolithography 发明人:KENNEDY JOSEPH T; BALDWIN-HENDRICKS TERESA 权利人:HONEYWELL INT INC 摘要:Anti-reflective coating materials for ultraviolet photolithography include at least one absorbing compounds and at least one pH tuning agent that are incorporated into spin-on materials. Suitable absorbing compounds are those that absorb around wavelengths such as 365 nm, 248 nm, 193 nm and 157 nm that may be used in photolithography. Suitable pH tuning agents not only adjust the pH of the final spin-on composition, but also influence the chemical performance and characteristics, mechanical performance and structural makeup of the final spin-on composition that is part of the layered material, electronic component or semiconductor component, such that the final spin-on composition is more compatible with the resist material that is coupled to it. A method of making absorbing and pH tuned spin-on materials includes combining at least one organic absorbing compound and at least one pH tuning agent with at least one silane reactant during synthesis of the spin-on materials and compositions.
