Synthesis and application of coumarin fluorescence probes

Abstract

In recent years, the research on fluorescent probes has developed rapidly.

Synthetic Routes to Coumarin(Benzopyrone)-Fused Five-Membered Aromatic Heterocycles Built on the α-Pyrone Moiety. Part 1: Five-Membered Aromatic Rings with One Heteroatom

“…On the other hand, coumarin represents an ingredient in perfumes [ 19 ], cosmetics [ 20 ], and as industrial additives [ 21 , 22 ]. Furthermore, coumarins play a pivotal role in science and technology as fluorescent sensors, mainly due to their interesting light-emissive characteristics, which are often responsive to the environment [ 23 , 24 , 25 , 26 ]. The coumarin (benzopyrane)-fused, membered aromatic heterocycles built on the α-pyrone moiety are an important scaffold.…”

A novel donor–π–acceptor halochromic 2,6-distyrylnaphthalene chromophore: synthesis, photophysical properties and DFT studies

“…This belonging plays an important role in the improvement of the photophysical properties of photonic devices. [9][10][11] Distyrylbenzenes are a well-known type of uorescent dyes that possess high photochemical and thermal stability. 12,13 To synthesize these conjugated spacers, two important organic transformations, namely Wittig and Heck reactions, are used.…”

7-Alkoxy-appended coumarin derivatives: synthesis, photo-physical properties, aggregation behaviours and current–voltage (I–V) characteristic studies on thin films

“…8 Coumarins structurally belong to a lactone family constructed with a benzene ring fused to an a-pyrone ring and essentially possess a conjugated system with electron rich and good charge transport properties. 9 The structural simplicity and versatility of the coumarin scaffold make them interesting starting point for a wide range of applications. They have been found to show versatile pharmacological and biological activities, [10][11][12][13][14][15] which can display anti-cancer, anti-HIV, anti-tumor, anti-microbial, antibacterial, anti-inammatory, anti-oxidant, anti-diabetic, anti-coagulant functions, etc.…”
