Dicyanovinyl-based fluorescent sensors for dual mechanism amine sensing

Abstract

We report two dual mechanism fluorescent sensors that enable selective sensing of alkyl primary amines with a low detection limit.

A solid-state fluorescent probe for α,β-diamine based on tetraphenylethylene skeleton construction

“…Comparing with monoamines and interference, the compound DPEC was much more sensitive to α,β-diamines during the same reaction time, which consisted with the previous report. 30…”

“…much more sensitive to a,b-diamines during the same reaction time, which consisted with the previous report. 30 The test strips of solid-state fluorescent sensor…”

A novel fluorescent probe of alkyne compounds for putrescine detection based on click reaction

“…1 Putrescine (DAB) is an important component of biogenic amines, an essential component of all living organisms and tissues. 2,3 Usually, putrescine is formed during the food processing/storage stages due to the bacterial activities. 4,5 High concentration of biogenic amines was observed in processed foods such as fish, wine, beer, meat products and in fermented foods.…”

Directedorthoand Remote Metalation–Suzuki–Miyaura Cross Coupling Route to Azafluorenol Core Liquid Crystals

“…Fluorene derivatives are of significant interest because of their attractive electronic and photophysical properties . They have been intensively studied as organic optoelectronic materials for OLEDs, OFETs, solar cells, and chemical sensors and as nonlinear optical materials and dyes . Fluorene derivatives can also be incorporated within metal organic frameworks, combining their photophysical capabilities with structural aspects enabling further functionalization, e.g., chiral fluorene ligands facilitate chiral molecular separation or catalysis …”
