Patent ID: 7078724

Claim:
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 C 2 –C 20 -alkyl radical, a monounsaturated or polyunsaturated C 2 –C 20 -alkenyl radical, a C 2 –C 20 -alkoxy radical, a C 2 –C 20 -aralkyl radical, a C 2 –C 20 -oligoether or C 2 –C 20 polyether radical, and a -C 10 H 21 radical, and n is an integer greater than or equal to 3.
