Publikováno v: Chemical Science

In this report it is shown that nitroacetic acid 1 (O2NCH2CO2H) can be conveniently used to control the pH of a water solution over time. Time-programmable sequences of the kind pH1(high)–pH2(low)–pH3(high) can be achieved, where both the extent

Publikováno v: Chemistry – A European Journal. 28

This work reports that the composition of a dynamic library (DL) of interconverting imines can be controlled over time in a dissipative fashion by the addition of an activated carboxylic acid used as a chemical fuel. When the fuel is added to the DL,

Dissipative control of the fluorescence of a 1,3-dipyrenyl calix[4]arene in the cone conformation

Autor: Daniele Del Giudice, Stefano Di Stefano, Alessandro Casnati, Roberta Cacciapaglia, Francesco Rispoli, Laura Baldini, Emanuele Spatola, Luciano Marchiò

The temporal control (ON/OFF/ON) of the fluorescence of a dichloromethane/acetonitrile 1 : 1 solution of calixarene 3 decorated with two pyrenyl moieties at the upper rim is attained by the addition of CCl3CO2H used as a convenient chemical fuel.

In this work, we report that 2-cyano-2-phenylpropanoic acid and its p-Cl, p-CH(3) and p-OCH(3) derivatives can be used as chemical fuels to control the geometry of the calix[4]arene scaffold in its cone conformation. It is shown that, under the actio
