摘　　要：合成了Sm(aa)(acac)2phen和Sm0.5Y0.5(acac)2(aa)两个单体,与丙烯酸甲酯共聚得聚合物P1和P2。在350 nm紫外光的激发下,聚合物发出645 nm的红光,与叶绿素a叶绿素b所需要的光吻合;用Y3+离子取代了部分Sm^3+离子,增强了Sm^3+离子荧光强度,解释了增强机理;聚合物P2与聚乙烯农膜相容性好,P2是一种潜在的农膜转光剂。Two monomers of Sm(acac)2(aa)phen and Sm 0.5 Y 0.5(acac)2(aa)phen were synthesized.Sm(aa)(acac)2phen-co-methyl acrylate(P1)and Sm 0.5 Y 0.5(acac)2(aa)-co-methyl acrylate(P2)copolymers were prepared.P1 and P2 emit 645 nm red light under excited at 350 nm UV light.The 645nm red light is suitable for photosynthesis of chlorophyll a and chlorophyll b of plants.Sm 3+fluorescence intensity is strengthened because of Y3+replacing some Sm 3+and explained strengthening mechanism.P2 and polytene has good compatibility.P2 is a kind of potential light-conversion agent of agricultural film.
