eng	AIE Luminogenes Based on Tripodal Triphenylamine and Carbazole Chromophores	Aggregation induced emission (AIE) refers to a photophysical phenomenon in a group of luminogenic materials that are non-emissive when dissolved in solvents where are highly soluble but become luminescent in solvents where is the solubility low as aggregates are formed. Such luminogenes are also emissive in solid state. From a structural point of view, compounds showing AIE are most often derivatives with a conjugated π-bond system. AIE luminogens have potential applications as sensitive chemical sensors, biological probes, semiconductors, organic light-emitting diodes (OLEDs), or light-emitting liquid crystals. Following our previous research, series of novel chromophores were synthetized using Suzuki-Miyaura cross-coupling reaction. These chromophores consists of the central electron donor (triphenylamine or carbazole) and peripheral acceptors in the form of nitro group(s) and (hetero)aromate(s) . Depending on the type of (hetero)aromatic acceptor, several synthesized derivatives showed emission based on the AIE mechanism. Due to the systematic structure study in the entire series (basic structures I – III), structure – property relations were elucidated.	chromophore; triphenylamine; carbazole; acceptor
