Pyrenyl lumophore

The structural mutation of our 29 by variation of the macrocycle (via its heteroatoms and carbon bridges), the lumophore, and the spacer is obviously a rich vein to mine for luminescent PET sensors. Kubo s laboratory (formerly at Kyushu University, now at Kanagawa University, Japan) has systematically explored this line [81-84], 33 has a straight swap of 1-pyrenyl for 9-anthryl [81]. 34 to 36 [81-83] use two nitrogens in the crown ether instead of the one in 29,...
