摘要：A facile, efficient synthesis of the novel cinnoline derivative (E)-2,2'-(3-((3-bromophenyl) imino)-5-(tertbutyl)-3H-pyrrolo[3,2,1-fi]cinnoline-2,8-diy1)bis(propan-an-2-01) (1) is reported. Richter cyclization of an o-ethynenearyldiazonium salt gave the cinnoline derivative which underwent a cyclization reaction to form the unexpected tricyclic compound 1. The absorption and fluorescence properties of cinnoline 1 were investigated in various solvents. A single crystal of 1 was grown and analyzed by X-ray diffraction analysis. The results showed that the inclusion compound was formed between the host (cinnoline 1) and the guest (acetone) in the crystal. (C) 2017 Elsevier Ltd. All rights reserved.
