Abstract:
A molecular tweezer incorporating two acridinium moieties linked by a 1,3-dipyridylbenzene spacer was synthesized in three steps. The formation of its self-complementary dimer in water was demonstrated as a result of π-π stacking and hydrophobic interactions. Moreover, a 1 : 1 mixture of this bis-acridinium tweezer with one built on a 2,6-diphenylpyridyl spacer evidenced its narcissistic self-sorting behaviour in water.

Characteristics of Narcissistic Personality Disorder
Narcissistic individuals exhibit an inflated sense of self-importance and an excessive need for admiration. They are often...
Nuclear Protein Sorting
Proteins targeted to the nucleus carry nuclear localization signals or NLS recognized by import receptors in the cytosol. Similarly, proteins with nuclear export signals are recognized by export receptors. Import and export receptors are...

Most of these mitochondrial proteins are encoded by the nucleus and imported to the mitochondria as unfolded or loosely folded precursors. Mitochondrial precursors...
Overview of Protein Sorting and Transport
Protein sorting can be of two types: signal-based sorting and vesicle-based trafficking. In signal-based sorting, specific amino acid sequences called sorting signals target proteins to the proper location inside the cell either via gated transport or by protein translocation. In gated transport, folded...
