Tweaking the Optoelectronic Properties of S‐Doped Polycyclic Aromatic Hydrocarbons by Chemical Oxidation

Abstract

Dedicated to Prof. Alain Krief on the occasion of his 80th birthday.

Dibenzannulated peri-acenoacenes from anthanthrene derivatives

“…Large polyaromatic hydrocarbons (PAHs) have been widely studied for their fundamental and optoelectronic properties. [1][2][3][4][5][6][7] Their tunable bandgap, planar geometry and ease of functionalization make them compounds of choice for organic electronics applications such as organic light emitting diodes (OLEDs), [8][9][10] organic photovoltaic devices (OPV), [11][12][13] and organic eld-effect transistors (OFETs). [14][15][16] Recently, zigzag-edged Kekulé and non-Kekulé PAHs such as annulated acenes, 17,18 triangulenes, [19][20][21] peri-acenes 22 and peri-acenoacenes [23][24][25][26] (Fig.…”
