title: Synthesis of C70-Based Fluorophores through Sequential Functionalization to Form Isomerically Pure Multiadducts.
abstract: Selective addition to the C70cage divides its π-conjugated system into various smaller π-conjugated systems with enhanced fluorescent properties. Key reactions include chlorination, methoxylation, ozonation, and Bingel or Bingel-Hirsch reactions. The maximum emission wavelength of the C70multiadducts ranges from 450 to 655 nm. Among the C70multiadducts, C70(OMe)8(C(COOEt)2)3showed the highest quantum yield (ΦF=0.18) and the largest Δ[λmax(emission)- λmax(absorption)] (402 nm), with maximum emission at 655 nm.
