Synthetic Route of 18531-99-2, Chemistry is the experimental science by definition. We want to make observations to prove hypothesis. For this purpose, we perform experiments in the lab. 18531-99-2, Name is (S)-[1,1′-Binaphthalene]-2,2′-diol,introducing its new discovery.
Mizoroki-Heck coupling polymerization of diiodonated 1,1?-binaphthyls (BINTL1/BINTL2) with 1,4-divinylbenzenes (DVB-H/DVB-Me/DVB-OMe) proceeded to afford poly(arylene vinylene ketone)s (PAVK1-6). Upon photoexcitation, PAVKs in solutions exhibit fluorescence behavior with large Stokes shifts, and the maximum emission wavelength (lambdaem) depends on the nature of the solvent. PAVK1 analogs, in which the ketone carbonyl units of PAVK1 are replaced by sulfone, methylene, and ketal ones, were synthesized. Fluorescence spectra of PAVK1 analogs clearly exhibit a blue shift from that of original PAVK1. The difference in behavior between PAVKs and PAVK1 analogs suggests that the fluorescence of PAVKs originates from donor-acceptor interaction between 1,4-distryrylbenzene skeletons and ketone carbonyl units, respectively.
