Catalysts function by providing an alternate reaction mechanism that has a lower activation energy than would be found in the absence of the catalyst. In some cases, the catalyzed mechanism may include additional steps.In a article, 18531-94-7, molcular formula is C20H14O2, introducing its new discovery. Recommanded Product: 18531-94-7
Two chiral binaphthyl-based enantiomers, (R/S)-7, were designed and synthesized by Sonogashira cross-coupling reaction of AIE-active TPE and O-BOPHY. Interestingly, the resulting (R/S)-7 can exhibit emission enlargement response in DCM/hexane mixtures due to AIE behavior, but fluorescence quenching in THF/H2O mixtures due to ACQ effect. (R/S)-7 can produce gradual reversal AICD (aggregation-induced circular dichroism) signals from solution to aggregation, which can be attributed to axial chirality transfer to self-assembled helical nanowires in aggregation state.
