Abstract
The invention relates to a polymeric micellar structure which comprising an ionic porphyrin dendrimer represented by general formula (1): q(c)PM (where 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, R1, R2, R3 and R4 are the same or different and represents hydrogen or identical or different aryl ether dendrosubunits, provided that at least one of R1, R2, R3 and R4 represent an aryl ether dendrosubunits and that each aryl ether dendrosubunit has an anionic or cationic group at the end optionally though a spacer molecule chain.
