Organic compounds having a core-shell structure

A compound comprising a core-shell structure comprising,

• (i) a core of multifunctional units, and
• (ii) a shell of linear conjugated oligomeric chains each consisting of a terminal capping group of a flexible nonconjugated chain,
• wherein, said core-shell structure of said compound is represented by the following formula (Z),
• wherein
• K represents said core having a functionality of n,
• L represents said linear conjugated oligomeric chain, said linear conjugated oligomeric chain being selected from the group consisting of representative formulas (VI-a), (VI-b) and (VI-c),
• wherein p in each case is 2 to 10, p being the same for each n linear conjugated oligomeric chain L,
• R represents the flexible nonconjugate chain of said terminal capping group, and is selected from the group consisting of a straight-chain or branched C2–C20-alkyl radical, a monounsaturated or polyunsaturated C2–C20-alkenyl radical, a C2–C20-alkoxy radical, a C2–C20-aralkyl radical, a C2–C20-oligoether or C2–C20polyether radical, and a -C10H21 radical, and
• n is an integer greater than or equal to 3.
