Modulation of the chemiluminescent signal from N10-(3-sulfopropyl)-N-sulfonylacridinium-9-carboxamides
摘要:
Acridinium salts 3a-h were synthesized from the corresponding sulfonamides la-h and their chemiluminescence profiles were compared. The quantity of light emitted over the time studied did not correlate well with the pK(a) of sulfonamide leaving group. Rather, steric factors contributed the most to modulating the light output from these compounds. The mesitylsulfonyl substituent of acridinium salt 3d reduced the chemiluminescence signal by 20-fold relative to the reference acridinium salt 3a. (C) 1999 Elsevier Science Ltd. All rights reserved.
