Chem Soc Rev
. 2015 Feb;
44(13):4203-11.
PMID: 25695939
Following a brief introduction to the principle of fluorescent PET (photoinduced electron transfer) sensors and switches, the outputs of laboratories in various countries from the past year or two are...

Angew Chem Int Ed Engl
. 2014 Feb;
53(14):3622-5.
PMID: 24574178
The fluorophore-spacer1-receptor1-spacer2-receptor2 system (where receptor2 alone is photoredox-inactive) shows ionically tunable proton-induced fluorescence off-on switching, which is reminiscent of thermionic triode behavior. This also represents a new extension to modular...

. 2012 Jul;
11(11):1675-81.
PMID: 22752208
Naphthalenic compounds are a rich resource for designers of fluorescent sensing/switching/logic systems. The degree of internal charge transfer (ICT) character in the fluorophore excited states can vary from negligible to...

Top Curr Chem
. 2011 Apr;
300:1-28.
PMID: 21516434
The competition between Photoinduced electron transfer (PET) and other de-excitation pathways such as fluorescence and phosphorescence can be controlled within designed molecular structures. Depending on the particular design, the resulting...

. 2011 Feb;
6(3):750-66.
PMID: 21290607
Chemists are now able to emulate the ideas and instruments of mathematics and computer science with molecules. The integration of molecular logic gates into small arrays has been a growth...

. 2010 May;
10(10):1267-73.
PMID: 20445879
The use of a water-soluble, thermo-responsive polymer as a highly sensitive fluorescence-lifetime probe of microfluidic temperature is demonstrated. The fluorescence lifetime of poly(N-isopropylacrylamide) labelled with a benzofurazan fluorophore is shown...

Nat Nanotechnol
. 2008 Jul;
2(7):399-410.
PMID: 18654323
Molecular substrates can be viewed as computational devices that process physical or chemical 'inputs' to generate 'outputs' based on a set of logical operators. By recognizing this conceptual crossover between...
