The 1,1′-binaphthol based oligomers 3 and 7 with 3,3′-acetylene-phenylene-acetylene spacer were prepared from BINOL 1. The high optical rotation value and CD spectra demonstrated the main chain chirality of the oligomer mol. The UV-VIS and fluorescent spectra evidence the characteristics of conjugated structure. In comparison with oligomer 2 bearing 3,3′-acetylene spacer, the oligomers 3 and 7 have longer efficient conjugation segment, and their fluorescent quantum yields (φ) increased (0.60-0.65 vs. 0.14). Extending the effective conjugation segment would improve the photophys. properties of chiral conjugated polymers. The results came from multiple reactions, including the reaction of (R)-3,3′-Diiodo-2,2′-bis(methoxymethoxy)-1,1′-binaphthalene(cas: 189518-78-3Application In Synthesis of (R)-3,3′-Diiodo-2,2′-bis(methoxymethoxy)-1,1′-binaphthalene)
(R)-3,3′-Diiodo-2,2′-bis(methoxymethoxy)-1,1′-binaphthalene(cas: 189518-78-3) belongs to organic iodides. The carbon-iodine bond is weaker than other carbon-halogen bonds due to the poor electronegative nature of the iodine atom. Alkyl iodides react at a faster rate than alkyl fluorides due to the weak C-I bond.Application In Synthesis of (R)-3,3′-Diiodo-2,2′-bis(methoxymethoxy)-1,1′-binaphthalene
