“…The development of π-conjugated luminescent aromatic and heteroaromatic organic molecules has drawn immense attention of the scientific and industrial communities due to modern applications such as organic light emitting diodes (OLED) [1][2][3], photovoltaic cells [4,5], lasers [6,7], nonlinear optical (NLO) [8,9], field effect transistors (FET) [10,11], sensors [12], photodetectors [13,14] and bioimaging [15,16]. Organic molecules with donor and acceptor groups in the same molecule that form a push-pull system, among the donor groups, phenothiazine (PTZ) [17,18], carbazole (CZ) [19], triphenylamine (TPA) [20,21], phenoxazine [22] and the acceptor groups, rhodanine [23,24], triazine [25,26], 1,3,4oxadiazole [27], play the role of forming the push-pull system.…”
