Novel azacrown ether containing blue-light emitting anthracene fluorophore, 9,10-bis[p-(1-aza-18-crown-6)methylphenyl]anthracene (3) and N,N-bis[9-(p-methylphenyl)anthracenylmethyl]-1,6-diaza-18-crown-6 (4) were prepared by reacting anthracene derivatives 1 and 2 with mono- and diaza-18-crown-6, respectively. Also, crown ether containing fluorophore copolymer (5) were prepared by reacting 1,6-diaza-18-crown-6 with 1. Their fluorescence emission spectral studies were investigated by binding group I, group II and various metal cations. The fluorophores showed an absorption at max＝372 nm and an emission at max＝430 nm. pH Dependency of fluoroscence emission intensity were examined to determine the optimum pH for the fluorophores.

Azacrown ether를 포함하는 청색발광 형광체, 9,10-bis[p-(1-aza-18-crown-6)methyl phenyl] anthracene(3)과 N,N-bis[9-(p-methylphenyl)anthracenylmethyl]-1,6-diaza-18-crown-6(4)를 안트라센 유도체 1과 2를 mono- 및 diaza-18-crown-6와 반응시켜 합성하였다. 역시 azacrown ether를 포함하는 형광체 공중합체(5)를 1,6-diaza-18-crown-6와 1을 반응시켜 합성하였다. 제 1족, 2족 그리고 여러 가지 금속 양이온을 결합시킴으로써 형광 발광세기 변화에 대한 연구를 진행하였다. 형광체는 max＝372 nm에서 최대흡수를 그리고 max＝430 nm에서 최대 발광을 보여주었다. 형광체들의 최적 pH 조건을 조사하기 위해 형광 발광 세기의 pH 의존성도 측정하여 하였다.
