aryl Grignard addition to 1-methyl-4-piperidone and direct aromatization of the resulting 4-aryl-4-piperidinols. The pyridines were N-alkylated to give sulfonate salts desired for their fluorescent properties. Study of selected compounds as laser dyes revealed several structures to be efficient dyes lasing in the 530-550 nm range. Two new diazaquaterphenyls were prepared and were quaternized. These salts
通过有效的两步法制备许多4-芳基吡啶,其中许多甲氧基被甲氧基取代,包括将芳基格利雅(Grignard)加到1-甲基-4-哌啶酮中,并将所得的4-芳基-4-哌啶醇直接芳构化。吡啶经N-烷基化,得到其荧光性能所需的磺酸盐。对选定化合物作为激光染料的研究表明,有几种结构是有效的染料,可发射530-550 nm范围的激光。制备了两个新的二氮杂四苯并进行季铵化。这些盐在420-450 nm范围内表现出强烈的荧光,但不会发光。适当取代激发态分子内质子转移(ESIPT)的酚氮杂三苯基根本不发荧光。
