Durene-capped porphyrins : synthesis and characterization
Wijesekera, Tilak P.,David, Shantha,Paine, John B. III,James, Brian R.,Dolphin David
, p. 2063 - 2071 (2007/10/02)
The synthesis of porphyrins having a fully hydrophobic cavity capped by a durene moiety is described.The size of the cavity is adjusted by varying the number of methylene -(CH2)n- groups linking the tetramethylphenylene cap with the diametrical
