抄録

Sixteen porphyrin rings were introduced to dendritic poly (L-lysine). The synthesis of lysine dendrimer was carried out starting with hexamethylenediamine and Boc-Lys (Boc) -OH. At the fourth generation, a lysine monomer containing a porphyrin ring, Boc-Lys (Por) -OH was coupled to introduce 16 porphyrin rings on the side chain of lysines. Further, the main chain was elongated to the sixth generation. The Boc-Lys (Por) -OH was also introduced at the third or fifth generation to allow different numbers of porphyrin rings to be stratified in the dendritic poly (L-lysine). These dendrimers were soluble in dimethyl formamide (DMF), dichloromethane (DCM), and tetrahydrofuran (THF). Circular dichroism (CD) spectra of the dendrimers gave no significant peaks in DMF. However, a strong split Cotton effect was observed increasingly in CD by the addition (>50%) of toluene. We presume that stratified porphyrins formed a chiral conformation in the dendrimer by a mixed solvent effect of DMF (good solvent for polypeptide) and toluene (good solvent for porphyrin).
