摘要

Abstract-Bithiophene chromophores were synthesized and used to derivatize NH2 and OH groups in aminocyclohexane,(IR, 2R)-diaminocyclohexane,(lR, 2R)-trans-l, 2- cyclohexanediol and methyl L-acosamidine for their application in the exciton chirality method. Schiff base, ester and amide derivatives were generated in good yields and were found to exhibit exciton-split CD curves. Besides their absorption at long wavelengths (red ...
