A method of generating reactive species which includes providing a wavelength-specific sensitizer associated with a reactive species generating photoinitiator, wherein the wavelength-specific sensitizer comprises a phthalic acid derivative or a phenyl-substituted aliphatic ketone derivative; and irradiating the wavelength-specific sensitizer. The sensitizer absorbs energy and transfers the absorbed energy to the photoinitiator, which, in turn, generates reactive species. The radiation to which the polymolecular photoreactor is exposed generally will have a wavelength of from about 4 to about 1,000 nanometers. Thus, the radiation may be ultraviolet radiation, including near ultraviolet and far or vacuum ultraviolet radiation: visible radiation: and near infrared radiation. Also described are methods of polymerizing unsaturated monomers and curing an unsaturated oligomer/monomer mixture.
一种产生反应物的方法,包括提供与产生反应物的光引发剂相关联的波长特异性敏化剂,其中波长特异性敏化剂包括邻苯二甲酸衍生物或苯基取代的脂肪族酮衍生物;以及照射波长特异性敏化剂。敏化剂吸收能量并将吸收的能量转移给光引发剂,光引发剂反过来产生反应物。聚合分子光反应器受到的辐射波长一般在 4 纳米到 1000 纳米之间。因此,辐射可以是紫外线辐射,包括近紫外线辐射、远紫外线辐射或真空紫外线辐射、可见光辐射和近红外线辐射。还描述了不饱和单体聚合和不饱和低聚物/单体混合物固化的方法。
