| Abstract |
The controlled preparation of well-defined distorted nanographenes by a bottom-up approach based on organic synthesis permits the direct establishment of unprecedented structure-property relationships in carbon nanostructures. The simultaneous incorporation of various defects in nanographenes affords highly curved structures with novel or enhanced photophysical properties. In this sense, we recently reported a fully helical and saddle-shaped nanographene ribbon containing the first undecabenzo[7]helicene unit. Both its linear and nonlinear optical properties are enhanced in comparison with those of other partially -extended [7]helicenes. Moreover, the new superhelicene exhibits the highest emission dissymmetry factor ( g(lum) ) reported to date for a homochiral nanographene. The combination of both nonlinear and chiroptical properties in nanographenes opens up new possible future applications for those distorted nanostructures. 1 Introduction 2 Synthesis of Embedded Seven-Membered Rings 3 Combination of Defects: Seven-Membered Rings and -Extended Helicenes 4 Conclusions and Outlook |
