Synthesis of Photoconductive N-unsaturated Alkylcarbazole Derivatives

광전도성 N-불포화알킬카르바졸 유도체의 합성

The N-unsaturated alkylcarbazole derivatives were synthesized by the nucleophilic unimolucular substitution reaction ($S_N1$) of carbazole with unsaturated alkyl chloride. These reactions between carbazole and unsaturated alkyl chloride were conducted in dimethyl sulfoxide (DMSO) containing alkali (NaOH or KOH) at room temperature for 4 hrs under nitrogen atmosphere. The mole ratios of carbazole, alkali and unsaturated alkyl chloride were 1:6:1, respectively. All of the compounds of starting materials and reaction products were characterized by CHN analysis, $^1H$-NMR and FR-IR spectroscopy.

N-불포화알킬카르바졸유도체는 카르바졸과 염화불포화알킬과의 친핵적1분자 치환반응 ($S_N1$)에 의해서 합성했다. 이들의 반응은 질소분위기하상온에서 알칼리 (NaOH 또는 KOH)를 함유한 DMSO용매중 카르바졸과 염화불포화알킬을 4시간에 걸쳐 행했으며, 이때 카르바졸에 대한 알칼리와 염화불포화알킬과의 몰비는 1:6:1이었다. 반응물질과 반응생성물은 모두 CHN원소분석, $^1H$-NMR 및 FT-IR에 의하여 측정되었다.
