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] -1,5-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 가지금속 양이온을 결합시킴으로써 형광 발광세기 변화에 대한 연구를 진행하였다. 형광체는 ${lambda}_{max}$=372nm에서 최대흡수를 그리고 ${lambda}_{max}$=430 nm에서 최대 발광을 보여주었다. 형광체들의 최적 PH 조건을 조사하기 위해 형광 발광 세기의 pH 의존성도 측정하여 하였다.
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) anthracenyl-methyl] -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 ${lambda}_{max}$= 372 nm and an emission at ${lambda}_{max}$= 430 nm. pH Dependency of fluorescence emission intensity were examined to determine the optimum pH for the fluorophores.
