Provided are a white-emitting monomolecular compound using excited-state intramolecular proton transfer (ESIPT) characteristics, and an organic electroluminescence device and a laser device comprising same. The white-emitting monomolecular compound according to the present invention is prepared by covalently bonding at least two types of molecules which produce different colors and have excited-state intramolecular proton transfer (ESIPT) characteristics. The white-emitting monomolecular compound according to the present invention achieves white luminescence irrespective of the concentration thereof and of the state of the materials thereof, and therefore can be used in a variety of fields including an organic electroluminescence device and a laser device.

Intramolecular three-centered hydrogen bonding has been used to induce dipyridyl anthranilamide 5 and diphenylacetylene anthranilamide 11 to adopt rigid straight conformation. Compound 5 reacted with Pd(dppp)(OTf)(2) (12a) or Pt(dppp)(OTf)(2) (12b) in dichloromethane to afford square metallocyclophanes 13a and 13b in 70% and 40% yield, respectively. In contrast, the reaction of 11 with 12b in dichloromethane gave triangular metallocyclophane 14 in 15% yield. (c) 2005 Elsevier Ltd. All rights reserved.
