چکیده

Laminated nanotapes were fabricated via conformation specific self-assembly of two N-annulated perylene derivatives (NPDs). The assemblies in solvated states were characterized using cryogenic transmission electron microscopy (cryo-TEM), and their nanostructures were modulated by the synergistic interactions of π-π stacking and hydrogen bonds.

Self-assembly of luminescent N-annulated perylene tetraesters into fluid columnar phases.

A new class of N-annulated perylene tetraesters and their N-alkylated derivatives has been synthesized. N-Annulated perylene tetraesters stabilize a hexagonal columnar phase over a broad temperature range. The hexagonal columnar phase exhibited by these compounds shows good homeotropic alignment with few defects. Annulation in the bay region of the perylene tetraesters enhanced the width of the...

Effect of side-chain substituents on self-assembly of perylene diimide molecules: morphology control.

Effect of side-chain substitutions on the morphology of self-assembly of perylene diimide molecules has been studied with two derivatives modified with distinctly different side-chains, N,N'-di(dodecyl)-perylene-3,4,9,10-tetracarboxylic diimide (DD-PTCDI) and N,N'-di(nonyldecyl)-perylene-3,4,9,10-tetracarboxylic diimide (ND-PTCDI). Due to the different side-chain interference, the self-assembly...

Metal ion templated self-assembly of crown ether functionalized perylene bisimide dyes.

Two new perylene bisimide (PBI) derivatives possessing crown ether receptors at the 1,7 bay-positions and solubilizing ionic imide substituents were synthesized and their self-assembly properties in the presence of different metal ions were studied, revealing highly selective barium ion templated self-assembly of 15-crown-5 functionalized PBI into H-type dimer aggregates.

Enhanced fluorescence sensing of amine vapor based on ultrathin nanofibers.

The fluorescence sensing of amine vapor was largely enhanced upon using ultrathin nanofibers, which were fabricated from N-(1-hexylheptyl)perylene-3,4,9,10-tetracarboxyl-3,4-anhydride-9,10-imide by a new self-assembly approach.

One-dimensional self-assembly of a water soluble perylene diimide molecule by pH triggered hydrogelation.

A water soluble perylene diimide molecule has been fabricated into nanofibers via a pH triggered hydrogelation route. The one-dimensional self-assembly is dominated by the intermolecular π-π stacking interactions in concert with the hydrogen bonding between the carboxylic acid side chains. The anisotropic electronic and optical properties observed for the nanofibers are consistent with the one-...
