PROBLEM TO BE SOLVED: To provide a new dendrimer molecule, and to provide a light emitter comprising the molecule. SOLUTION: This compound represented by formula I [R<SP>1</SP>and R<SP>2</SP>are each H or methyl; M is the monovalent ion of Au, Ag or Cu; (n) is an integer of 2 to 4]. For example, a compound of formula II (R is n-C<SB>18</SB>H<SB>37</SB>) is exemplified. The molecule aggregate is changed into an aggregation state dependent on temperature, and emits light having a wavelength characteristic to the aggregation state. Further, the aggregation state of the molecule aggregate is reversibly changed into various aggregation states by the change of temperature. COPYRIGHT: (C)2004,JPO
