“…43 These chromophores providing powerful absorption (q 419 = 350,000) allowed measurements of exciton CD spectra for cases 44 when the interacting chromophores were separated by a distance of 50 Å . The q max value for carotenoids is around 100,000, so according to theory, 15 about 10 times smaller A values may be expected for identical distance and orientation.…”

“…In addition, the literature reports the possibility to enhance the circular dichroism (CD) sensitivity of chiral compounds through their derivatization with 5-(4-methylcarboxy-phenyl)-10,15,20-triphenylporphyrin and/or its zinc analog [8][9][10]. Thus, resulting powerful, versatile and multifaced chromophores for CD studies, porphyrins have been employed also in the field of molecular and chiral recognition [11,12], as well as absolute configuration assignment [13][14][15][16][17][18][19][20][21].…”

“…They have been introduced as selective probes in complex molecules, providing a sensitive means of investigating stereochemistry through exciton-coupling analysis. [10] Thus, the electronic and CD spectra will also be discussed.…”
