Abstract

A novel organic fluorescent material, namely 2,6-di([1,1'-biphenyl]-4-yl)-4-(perfluorophenyl)hepta-1,6-diene-1,1,7,7-tetracarbonitrile (DBPDT), has been synthesized and characterized in this study. Due to the special molecular packing mode in the solid state, J-aggregation, DBPDT displayed red-shifted emission compared with that in dilute solution. In this study, it was found that DBPDT showed aggregation-induced enhanced emission (AIEE) and solvatochromic properties. Assisted by quantum chemistry calculations, optical response properties to external electric field (EEF) were investigated, where it was found that external electric field (EEF) would affect the structures and optical properties of DBPDT distinctly. The optical response characteristics of DBPDT can provide an alternative structure for constructing advanced photoelectric functional materials.

Graphical abstract

A novel organic fluorescent material, namely 2,6-di([1,1'-biphenyl]-4-yl)-4-(perfluorophenyl)hepta-1,6-diene-1,1,7,7-tetracarbonitrile (DBPDT), has been synthesized and characterized in this study. Assisted by quantum chemistry calculations, optical response properties to external electric field (EEF) were investigated, where it was found that external electric field (EEF) would affect the structures and optical properties of DBPDT distinctly.

一种新型有机荧光材料：合成、结构和光学响应特性

本研究合成了一种新型有机荧光材料，即 2,6-二([1,1'-联苯]-4-基)-4-(全氟苯基)庚-1,6-二烯-1,1,7,7-四甲腈（DBPDT），并对其进行了表征。由于固态下特殊的分子堆积模式--J-聚集，DBPDT 与稀溶液相比显示出红移发射。研究发现，DBPDT 具有聚集诱导增强发射（AIEE）和溶解变色特性。在量子化学计算的辅助下，研究了DBPDT对外部电场（EEF）的光学响应特性，发现外部电场（EEF）会对DBPDT的结构和光学特性产生明显的影响。图文摘要本研究合成并表征了一种新型有机荧光材料，即 2,6-二([1,1'-联苯]-4-基)-4-(全氟苯基)庚-1,6-二烯-1,1,7,7-四腈（DBPDT）。在量子化学计算的辅助下，研究了外电场（EEF）的光学响应特性，发现外电场（EEF）会对 DBPDT 的结构和光学特性产生明显的影响。

期刊介绍： Journal of Chemical Sciences is a monthly journal published by the Indian Academy of Sciences. It formed part of the original Proceedings of the Indian Academy of Sciences – Part A, started by the Nobel Laureate Prof C V Raman in 1934, that was split in 1978 into three separate journals. It was renamed as Journal of Chemical Sciences in 2004. The journal publishes original research articles and rapid communications, covering all areas of chemical sciences. A significant feature of the journal is its special issues, brought out from time to time, devoted to conference symposia/proceedings in frontier areas of the subject, held not only in India but also in other countries.
