Academic graphical abstract, theme: iodine(I)/iodine(III)-catalyzed 1,4-difluorination of Z/E-dienes, overall color scheme: blue-white + light gray, concise and professional. Left part: core catalytic cycle, showing the transformation pathway of iodine(I) and iodine(III), labeled "Sustainable catalysis, activity comparable to transition metals". Middle part: main reaction process, Z/E-diene substrates generate E-type 1,4-difluorinated products via catalysis, labeled "1,4-regioselectivity, E-configuration preference". Right part: enantioselectivity, chiral halogen bond + hydrogen bond network drive the formation of S-enantiomer, labeled "S-enantiomer, 92% ee". Background with simple chemical structure pattern, no redundant decorations, in line with ACS/Angew journal graphical abstract specifications, high-definition, clear lines, professional color matching.请根据以上内容生成一个图文摘要图
