Ghasemi, Z. Fathi Introduction The design and synthesis of fluorescent organic compounds have always been of extreme interest because of their high technology applications [1–5]. p-Conjugated molecules containing aromatic heterocycles have also attracted particular attention due to their widespread use in optical systems such as organic light-emitting diodes (OLEDs) [6–8], optical sensors [9, 10], dye-sensitized solar cells [11], fluorescent colorants [12–14] and fluorescent biological labels [15, 16]. The imidazole ring with desirable electron-rich characteristic and unique structural feature is widely present in natural and synthetic molecules [17]. 1,2,4,5-Tetraarylimidazoles, which can be prepared by four-component condensation of aromatic aldehydes, benzil, primary amines and ammonium acetate [18–20], have been considered as light-emitter scaffolds [21, 22]. Furthermore, pharmaceutical and biological activities of these polyaromatic compounds should not be ignored [23–28]. On the Research on Chemical Intermediates Springer Journals
