An All-Photonic Molecule-Based Parity Generator/Checker for Error Detection in Data Transmission
摘要:
The function of a parity generator/checker, which is an essential operation for detecting errors in data transmission, has been realized with multiphotochromic switches by taking advantage of a neuron-like fluorescence response and reversible light-induced transformations between the implicated isomers.

A series of novel N-substituted, thermally stable photochromic fluorescing 2-indolylfulmides were synthesized with high yields (>80%) from the corresponding fulgides by Lewis acid and hexamethyldisilazane-promoted one-pot reaction.
The photochromic fluorescence switching of a fulgimide derivative was used to implement the first molecule-based D (delay) flip-flop device, which works based on the principles of sequential logic. The device operates exclusively with photonic signals and can be conveniently switched in repeated cycles.
