AI Article Synopsis
- - Two new coumarin-based [5]helicene derivatives (3a and 6a) were synthesized and their structures characterized, with 3a's structure confirmed via single crystal X-ray analysis.
- - Both derivatives show green fluorescence when dissolved in dichloromethane, and 3a can form nanowires through re-precipitation.
- - The nanowire films made from 3a exhibit significantly better photoelectric conversion properties compared to films made from bulk 3a, highlighting the importance of ordered nanostructures for improved device performance.
Article Abstract
Two novel coumarin-embedded π-extended [5]helicene derivatives (3a and 6a) have been strategically synthesized and characterized, and the structure of 3a was determined single crystal X-ray analysis. Both of them exhibit green fluorescence in dichloromethane. In addition, molecule 3a can aggregate to form a large quantity of nanowires through the re-precipitation method. More importantly, the photoelectric conversion properties of 3a nanowire-C based films are much better than those of the thin film of bulk 3a-C, indicating that the ordered nanostructures are a crucial factor for enhancing device performance.

Gold is classified as a heavy metal, and its ion (Au) can manifest adverse impacts on ecological and human health. Thus, an effective method for Au detection is highly required. In this work, a new [5]helicene-based fluorescence sensor (M202P) was synthesized and applied for Au monitoring in near-perfect aqueous media.

A new fluorescence probe based on [5]helicene derivative (MT) was designed and synthesized. The chemical structure of the probe was fully characterized by NMR, mass spectrometry and X-ray crystallography. MT which is the combination of thioamide[5]helicene with Schiff base-thiophene moiety, exhibited a high selectivity to detect Hg through irreversible desulfurization reaction with "TurnON" fluorescence response and large Stokes shift of 110 nm in aqueous methanol solution.

In this paper, a tetrahydro[5]helicene-based imide dye with thienyl group (THID) was studied on its solvatochromism and aggregation-induced emission (AIE) properties by dissolved in various organic solvents. The linear relationship between Stokes shift and aprotic solvent polarity parameter was well fitted with Lippert-Mataga model. Furthermore, Stokes shift also were positively correlated with the normalized molar electronic transition energy, suggested that THID exceptionally depends on solvent polarity for twisted intramolecular charge transfer.

Article Synopsis
- A new fluorescent sensor, M201-DPA, allows for the selective detection of Cu and Zn in various solutions without interference from other ions.
- In HEPES buffer, it shows fluorescence quenching at 524 nm for Cu, while in Tris buffer/methanol, it exhibits fluorescence enhancement at 448 nm for Zn.
- M201-DPA achieves low detection limits for Cu and Zn, making it more sensitive than current drinking water standards set by the U.S. EPA and WHO.
