This invention regards, the unsaturated jipirometenboronhou carbon and fluorescence or fluorescence or electro- luminecsent analysis formula (i) the use for. Fluorescent quality including arrangement n b n , is offered by the ring which is on the center of 6 carbon atoms which become, R1 - R7 quality of chemical compound (firefly luminescence wave length, fluorescent quantum efficiency) makes modification possible, substituent S1 and S2 as for one side we have possessed the end group of coloration group at least, this, coloration substituent A makes that the molecule excites at close wave length possible, as for this, desirably, being the coloration substituent which possesses the wave length which is close to those of the ultraviolet ray, those which make Stokes shift power increase, the empty is selected.本発明は、式(I)の不飽和ジピロメテンボロンホウ素炭素及び蛍光又は蛍光若しくはエレクトロルミネセント解析のためのその使用、に関する。蛍光特性は配列-N-B-N-を含んで成る6個の炭素原子の中心にある環によって供され、R1~R7は化合物の特性(蛍光発光波長、蛍光量子収率)の変更を可能にし、置換基S1及びS2の少なくとも一方は発色団の末端基を有しており、これが、発色置換基Aと近い波長で分子が励起するのを可能にし、これは、好ましくは、紫外線のものに近い波長を有する発色置換基であって、ストークスシフトを強力に増大させるもの、から選択される。
