使用2-四氢萘酮和取代的水杨醛有效地合成了一系列弱发射,出射态的分子内质子转移活性四氢二苯并[a,i]菲蒽基-5-基)酚。这些染料与三氟化硼二乙基醚化物平滑配位,生成π-共轭和刚性四配位的硼-菲啶配合物。配合物在溶液和固态中具有高发射率,斯托克斯位移值范围从6190至10410 cm -1和中等的荧光量子产率。一项系统的光物理和溶剂变色研究表明,硼苯菲啶的分子内电荷转移过程比其他方法更有效,这得到了DFT研究的支持。此外,电化学研究证明了这些硼配合物的高电子接受能力。
A series of weakly emissive, exited state intramolecular proton transfer active tetrahydrodibenzo[a,i]phenanthridin-5-yl)phenols were efficiently synthesized using 2-tetralone and substituted salicylaldehydes. These dyes were smoothly coordinated with boron trifluoride diethyletherate resulting in π-conjugated and rigid tetracoordinated boron-phenanthridine complexes. The complexes were highly emissive

A simple and optically responsive chemosensor for the detection of Al3+ and Cr3+: In live cells and real sample analysis
Abstract A simple and efficient synthesis of phenanthridine molecule has been successfully achieved. This is involved in the development of fluorescent chemosensor for the trace level determination of Al3+ and Cr3+ through a turn-on response. The recognizing pathway towards Al3+ and Cr3+ was investigated by UV visible spectrometry, Fluorescence spectrometry, NMR spectrometry and HR-MS. The calculated
