大单层囊泡(100 nm)被功能化以获得能够在纯水介质中光上转化的超分子颗粒。利用二苯基镧(DPA)在420 nm处的三重湮灭导致延迟荧光,将嵌入金属配合物敏化剂吸收的光上转换。脂质类型和发色团在膜中的位置影响TTA强度,TTA强度在较大浓度范围内保持不变。
Large unilamellar vesicles (100 nm) were functionalised to obtain supramolecular particles capable of light upconversion in pure aqueous media. Triplet–triplet annihilation of diphenylanthracene (DPA) leading to delayed fluorescence at 420 nm was used to up-convert the light absorbed by embedded metal complex sensitisers. The lipid type and the chromophore position in the membrane affect the TTA intensity, which remains constant over a large concentration range.
