Positive allosteric binding behavior of pyrene-appended triazole-modified thiacalix[4]arene-based fluorescent receptors [PDF]
The novel heteroditopic receptors 5a∼c have been synthesized, which bear a thiacalix[4]arene in the 1,3-alternate conformation. Two urea moieties possessing various aryl groups with either electron-donating or -withdrawing groups at their p-positions ...

Capacitive Pixelated CMOS Electronic Nose
A 1024‐pixel CMOS capacitive E‐nose with inkjet‐printed MOFs and polymer layers yields gas‐specific capacitance fingerprints under humid conditions, discriminating toluene from 2‐butanone at low power. ABSTRACT Although some of the human senses can nowadays be replaced by low‐cost electronic sensors such as microphones and image sensors, a compact low ...

Self-assembly of multi-component fluorescent molecular logic gates in micelles [PDF]
A recent strategy for developing supramolecular logic gates in water is based on combinations of molecules via self-assembly with surfactants, which eliminates the need for time-consuming synthesis. The self-assembly of surfactants and lumophores and
