A molecular photoionic AND gate based on fluorescent signalling
TLDR
A receptor is described that operates as a logic device with two input channels: the fluorescence signal depends on whether the molecule binds hydrogen ions, sodium ions or both and the input/output characteristics of this molecular device correspond to those of an AND gate.Abstract:
MOLECULES that perform logic operations are prerequisites for molecular information processing and computation1–11. We12,13 and others14–16 have previously reported receptor molecules that can be considered to perform simple logic operations by coupling ionic bonding or more complex molecular-recognition processes with photonic (fluorescence) signals: in these systems, chemical binding (the 'input') results in a change in fluorescence intensity (the 'output') from the receptor. Here we describe a receptor (molecule (1) in Fig. 1) that operates as a logic device with two input channels: the fluorescence signal depends on whether the molecule binds hydrogen ions, sodium ions or both. The input/output characteristics of this molecular device correspond to those of an AND gate.read more

Single pentacene molecules detected by fluorescence excitation in a p-terphenyl crystal.
Michel Orrit,J.-P. Bernard +1 more
TL;DR: Experiments clearly prove that narrow peaks in the fluorescence excitation spectrum of a pentacene-doped p-terphenyl crystal stem from single molecules, and show the feasibility of the optical study of a single molecule and its local environment.
