In this compound, its color tone of emitted light can be variously changed by altering the number of the thiophenering and the benzene (or naphthalene)-ring and the bonding order of the rings. Thus, if this molecular compound is used as a luminous material, it is possible to easily cope with both control of its luminous color and realization of highly efficient and bright luminescence. Use of a luminous material using this molecular compound makes it possible to realize luminescence having wide colors from violet to red highly efficiently.
