Synthesis and fluorescence emission properties of 1,3,6,8-tetraarylpyrenes

Abstract: Three types of stable pyrene-based highly fluorescence (blue) compounds, 1-, 1,6-bis, 1,8-bis and 1,3,6,8-tetrakis(7-tert-butylpyrenyl)pyrenes and 1, 3,6,8-tetrakis[9,9-bis

“…In recenty ears, there has been great interesti nb otht he design and synthesis of new pyrene derivatives, especially in the context of organic electronics. Pyrene derivatives can be appliedi ne lectronic devices such as organic light-emitting diodes (OLEDs) [1][2][3][4][5][6] and organic field-effect transistors (OFETs), [7][8][9] as well as in organic photovoltaic cells (OPVs) [10] and liquid crystalline materials. [11] This broad range of applications comes from the highly p-conjugated system of the pyrene core, which provides desirable photophysical and optical properties.…”

“…The acetyl functional group is located at the 2-position of pyrene. The C-O bond lengths are 1.2229(15) Å and 1.2200 (14) Å, respectively in the two independent 2-acetyl pyrene molecules, which is the typical double bond distance of an acetyl group. The C1-C3 and C19-C21 bond lengths are 1.4931(17) Å and 1.4937(17) Å, respectively, which are slightly smaller than those C1-C2 and C19-C20 bond lengths, indicating the π-π conjugation effect between pyrenyl moiety and the carbonyl group.…”

“…Many interesting pyrene-based functional materials have been reported to be used as important organic semiconductors for the applications in organic light-emitting diodes (OLEDs), organic field-effect transistors (OFETs), and organic photovoltaic devices (OPVs) [8][9][10][11]. However, the derivatization of pyrene almost focus on 1position, or 1-, 3-, 6-, and 8-positions [12][13][14][15]. There are few reports concerning 2-substituted pyrene derivatives due to its hard synthesis [16][17][18].…”
