implication of carbazole scaffolds in medicinal chemistry, photoelectronic materials and chromophores, the molecules containing the carbazole motif have attracted significant attention over the years. In this work, the vibronic contributions to carbazole structures could facilely change the solvatochromic effect, absorption wavelength, emission wavelength, and Stokes shifts of six 2-carbonyl carbazole ketones
由于咔唑支架在药物化学、光电材料和发色团中的广泛应用,含有咔唑基序的分子多年来引起了人们的广泛关注。在这项工作中,电子振动对咔唑结构的贡献可以很容易地改变六种2-羰基咔唑酮荧光团的溶剂化变色效应、吸收波长、发射波长和斯托克斯位移。其中,1-(1-甲基-9H-咔唑-2-基)乙酮(3a)的结构通过单晶XRD研究得到证实。研究了2-羰基咔唑酮3a的Fe(III)离子的比率检测。此外,推测化学传感器3a对Fe 3+阳离子的识别依赖于其刚性结构和共轭体系的良好共面性以及3a强的分子内电荷转移。
