Amine Sensing with Distyrylbenzenes and Their Hexamethylene-Linked Polymers: Spraying Them On

Abstract

We herein describe synthesis and property evaluation of two aldehyde-appended nonconjugated distyrylbenzene polymers as amine sensing platforms and compare their performance to that of their monomers. The monomers and polymers were dissolved in organic solvents and spraydeposited onto silica gel and neutral alox TLC plates so as to give small strip-shaped sensor arrays. With these, differential amine detection was achieved; we find that a neutral silica gel support is better able to discern the amines than alox TLC plates.

Water‐Soluble Fluorescent Probes for Selective Recognition of Lysine and Its Application in an Object Carry‐and‐Release System

“…Several approaches towards selective sensors for aliphatic amines, which provide strong optical signal changes in absorbance and fluorescence, have been presented in recent decades . Taking one representative example, aldehyde moieties could be employed as effective receptors capturing the analytes of amines, and producing large changes in fluorescence . Therefore, we decided to develop an optical chemosensor with formyl groups as receptors to react with amines.…”

Multipurpose made colorimetric materials for amines, pH change and metal ion detection

“…41 Therefore, several types of sensing materials based on uorescent probes, nanobers, lms of ZnS/PTCDA and TiO 2 /porphyrin with various detection limits and reversibility have been developed. [42][43][44][45][46][47][48][49][50][51] Polydentate hydrazones are conformationally exible ligands, and their structural features display versatile behaviour in metal coordination. For this study, we have chosen compounds 1-3 as they have several structural advantages (Fig.…”

Phenanthridine‐Based Donor/Acceptor Fluorescent Dyes: Synthesis, Photophysical Properties and Fluorometric Sensing of Biogenic Primary Amines

“…Hydrophobic porphyrin dyes, [61] trifluoromethyl-substituted ketones and some specific 1,3-diketones are a few fluorescent probes that displayed their application for amine recognition. [62] However, the sensing of BAs by using these probes are performed in organic solvent medium and is therefore unfeasible for biological applications. [63][64][65][66][67][68] Phenanthridines are among the essential nitrogen-containing heterocyclic compounds owing to their excellent optical properties, including narrow emission bandwidth, higher molar extinction coefficient and sensitivity to the solvent medium.…”
