• , a strong photoluminescence was observed for DBC-H and DBC-Si. Keywords: DFT calculation; dibenzo[g,p]chrysenes; fluorescent compounds; oxidation; polycyclic aromatic hydrocarbon (PAH); twisted acenes; Introduction Polycyclic aromatic hydrocarbons (PAHs) have attracted interest as potential

• . Conversely, the LUMO level of the highly twisted DBC-H(56°)-2 was 0.05 eV lower than the less twisted DBC-H. As a result, the HOMO–LUMO gap of DBC-H(56°)-2 becomes smaller than that of DBC-H. This is consistent with the trend reported for twisted acenes [57]. The conformational effect of the MeO group was

• electronic and optoelectronic materials [1][2][3][4][5][6][7][8][9][10][11][12]. Non-planar PAHs have been extensively investigated from the viewpoint of their synthetic challenge and/or for the development of functional organic materials [13][14][15][16][17][18][19][20][21][22]. Among such PAHs, twisted
