| Abstract: | The association of tetrakis(4-N-methylpyridyl)porphine with salmon testes DNA in solution has been investigated in the presence of ethanol at 25 degrees C. It was found that the association constant was 1.14 x 10(6) M-1 and it increased with increasing the mole fraction of added ethanol. The behavior was very different from that in the case of usual intercalaters. |
