Patent ID: 6949620

Claim:
A polymeric micellar structure comprising an ionic porphydrin dendrimer represented by general formula [1] q(c)PM [1] (wherein q represents the number of charged atoms on the periphery of the dendrimer, c represents a negative (−) or positive (+) charge; and PM is represented by the following general formula [2]; wherein M represents two hydrogen atoms or a metal atom; and R 1 , R 2 , R 3 and R 4 represent a hydrogen atom or aryl ether dendro-subunits that may be identical or different, at least one of R 1 , R 2 , R 3 and R 4 is an aryl ether dendro-subunit, which is represented by the following general formula [3]; wherein R and R′ each represent a hydrogen atom or a hydrocarbon group and may be identical or different, W represents an anionic group when the charge c is negative (−), or W represents a cationic group when the charge c is positive (−), each W may be bound by a spacer molecule chain, and n represents an integer) and a water-soluble polyaminoacid-type polymer.
